Function Documentation

void AdmError_create (AdmError ** error, int num, const char * format, ...)

Constructor/allocator for our AdmError structure. Fails safely and silently if error is NULL.

Parameters:

: error The pointer to the AdmError pointer in which the newly allocated AdmError structure will be returned.
num The integer error code of the new AdmError structure.
format The output format in printf(3) format.
... The variable arguments for the printf(3) format.

void AdmError_ref (AdmError * error)

Parameters:

: error The pointer to the AdmError structure to be deallocated.

void AdmError_unref (AdmError * error)

Decrements the reference count of the given AdmError function, and deallocates it when the count reaches 0. This function must only be called by reference holders.

Parameters:

: error The pointer to the AdmError structure to be deallocated.

const char* AdmError_strerr (AdmError * error)

Returns the error string of the given AdmError structure. The error string returned is guaranteed for only as long as the AdmError is refed. Users that want a copy, should make one.

Parameters:

: error The pointer to the AdmError structure.

Returns:

: The character string that contains the description of the error of the given AdmError structure.

Note:

: Based on the strerror(3) *NIX C library.

int AdmError_errno (AdmError * error)

Returns the error code of the given AdmError structure.

Parameters:

: error The pointer to the AdmError structure.

Returns:

: The int error code of the given AdmError structure. See admerror.h for a list of valid error code.

Note:

: Based on errno(3) *NIX C library.

See also:

: AdmError

AdmRefStr* AdmRefStr_ref (AdmRefStr * refstr)

void AdmRefStr_unref (AdmRefStr * refstr)

size_t AdmRefStr_len (AdmRefStr * refstr)

AdmRefStr* AdmRefStr_get (const char * str, int force)

Parameters:

: str the string to match the AdmRefStr to
force if we should create a matching AdmRefStr if one does not already exist

Returns:

: the unique matching AdmRefStr, or NULL if there is no match

AdmRefStr* AdmRefStr_nget (const char * str, size_t len, int force)

Parameters:

: str the string to match the AdmRefStr to
len the lenght of the string, as strlen would report it
force if we should create a matching AdmRefStr if one does not already exist

Returns:

: the unique matching AdmRefStr, or NULL if there is no match

AdmContext* AdmContext_new (const char * name, unsigned int serial, AdmError ** error)

AdmContext_new: create a new AdmContext element.

This function creates a new AdmContext element. Its root id node will be initialized using the passed name and serial. The returned AdmContext will be given a ref for the caller.

Parameters:

: name The name of the new AdmContext.
serial The serial number of the new AdmContext.
error Optional pointer to AdmError pointer.

Returns:

: The pointer to the new AdmContext element or NULL on failure.

AdmContext* AdmContext_ref (AdmContext * context, AdmError ** error)

: base64_scalar a pointer to an AdmBase64 element
value a pointer to a void pointer to return the address of the new buffer.
error an optional AdmError

Returns:

: the size of the new buffer.

This function will decode and return a copy of the binary string stored in a AdmBase64 element. You must free the returned buffer.

int AdmBase64_setBinValue (AdmBase64 * base64_scalar, const void * value, size_t size, AdmError ** error)

This function is used to set the binary value of an AdmBase64 string element. It stores an encoded copy of the value string it is passed.

Parameters:

: base64_scalar a pointer to an AdmBase64 element
value a pointer to a binary string
size the size of the binary string
error an optional AdmError

Returns:

: -1 on error, 0 on success

AdmRefStr* AdmCopy_getValue (AdmCopy * copy_scalar, AdmError ** error)

This function is used to request the path of an AdmCopy element. The string returned must be considered const and volatile, and if it is needed for long periods of time, the programmer should copy it.

Specifically, it is guranteed for only so long as the AdmCopy element is refed, and its value is not changed.

Parameters:

: copy_scalar a pointer to an AdmCopy element
error an optional GError

Returns:

: An AdmRefStr containing the AdmCopy's path

int AdmCopy_setValue (AdmCopy * copy_scalar, const char * value, AdmError ** error)

This function is used to set the path of an AdmCopy element. It stores a copy of the string passed to it, after checking its path validity.

Parameters:

: copy_scalar a pointer to an AdmCopy element
value a pointer to a valid path string
error an optional GError

Returns:

: -1 on error, 0 on success

Returns:

: the cache dir

Note:

: you do not own the return stritg, and must not free it

int AdmBlackBox_setCacheDir (const char * path, AdmError ** error)

Sets the cache directory the alchemist is currently using.

Parameters:

: path the cache directory you want to use
error an optional pointer to an AdmError pointer

Returns:

: -1 on failure, 0 on succes

Note:

: passing NULL as the path resets the path to the default

error Optional pointer to AdmError pointer.

AdmContext* AdmBlackBox_read (AdmBlackBox * box, AdmError ** error)

Tries to read the most current context from the given AdmBlackBox and return it. The BlackBox may not be able to be readable in which case NULL will be returned. Also it may allow caching and do so transparently.

Parameters:

: box The AdmBlackBox to read from.
error Optional pointer to AdmError pointer.

Returns:

: The pointer to the AdmContext retrived through the given box.

int AdmBlackBox_listSerial (AdmBlackBox * box, unsigned int * array, unsigned int array_len, unsigned int top_serial, AdmError ** error)

Creates a list of serial numbers of the given AdmBlackBox subject to the constraints.

Parameters:

: box The AdmBlackBox to get the list of serial numbers from.
array The pointer to the preallocated array of int values to be filled with the serial numbers.
array_len The size of the perallocated array.
top_serial The highest serial number that we request. Only serial numbers below that will be returned. Use 0 to request the newest (highest) serial numbers.
error Optional pointer to AdmError pointer.

Returns:

: The amount of serial numbers filled in. Always less or equal to the array length.

Note:

: The list of serial numbers can partially come from the local cached BlackBoxes as well.

AdmContext* AdmBlackBox_readSerial (AdmBlackBox * box, unsigned int serial, AdmError ** error)

Reads a context from the given AdmBlackBox with the specified serial number.

Parameters:

: box The AdmBlackBox to read the context from.
serial The serial number of the context we request.
error Optional pointer to AdmError pointer.

Returns:

: The pointer to the AdmContext retrived through the given box or NULL if no context with that serial number exists.

int AdmBlackBox_write (AdmBlackBox * box, AdmContext * context, AdmError ** error)

Write the given AdmContext to the given AdmBlackBox. Does automatic caching if the given AdmBlackBox supports it.

Parameters:

: box The AdmBlackBox to write to.
context The AdmContext to be written to the box.
error Optional pointer to AdmError pointer.

Returns:

: 0 on success, all other values indicate an error.

unsigned int AdmBlackBox_getMark (AdmBlackBox * box, const char * mark, AdmError ** error)

Get the serial number of the given AdmBlackBox for the given mark. The whole business with marks allows us to 'tag' cached boxes and to identify if they are dirty or not.

Parameters:

: box The AdmBlackBox from which to get the marked serial.
mark The mark string.
error Optional pointer to AdmError pointer.

Returns:

: The serial number of the marked cached box or 0 if no marked cached box exists.

int AdmBlackBox_setMark (AdmBlackBox * box, const char * mark, AdmError ** error)

Mark the given AdmBlackBox. The serial number is extracted from the given AdmBlackBox automatically. Any existing mark will be overwritten. If an AdmBlackBox is cached, then it is possible to mark it. This provides a mechanism for marking the top serial number in the cache down at a given mark, which is a string; allowing various applications to check to see if an interface has changed since the last time the accessed by doing something along the lines of:

 AdmBlackBox_setMark(box_p, 'app1_mark_string', error);
 ...
 int i;
 if ((AdmBlackBok_listSerial(box_p, &i, 1, 0, NULL) &&
        (i != AdmBlackBox_getMark(box_p, 'app1_mark_string', NULL)) {
        ...
 }

Parameters:

: box The AdmBlackBox which we want to mark.
mark The mark string.
error Optional pointer to AdmError pointer.

Returns:

: 0 on success, all other values indicate an error.

Clear the mark for the given AdmBlackBox.

Parameters:

: box The AdmBlackBox where we want to clear its mark.
mark The mark string.
error Optional pointer to AdmError pointer.

Returns:

: 0 on success, all other values indicate an error.
