Function Documentation

int fdbfs_field_add_image (  const char *  name, const char *  fmtname, fields_t **  th, fields_t **  tc, void *  value, size_t  sz )

Add image element to fields_t list. Parameters: name  Name of element. fmtname  Friendly name of element. [in,out]  th  Pointer to pointer containing address of head of list (will initialise if NULL) [in,out]  tc  Pointer to pointer containing address of last element on list (will set to last element). value  The value to set the element to. (not copied) sz  The length of the data. Returns: 0 on error (*th and *tc will remain unchanged)

int fdbfs_field_add_int (  const char *  name, const char *  fmtname, fields_t **  th, fields_t **  tc, int  value )

Add integer element to fields_t list. Parameters: name  Name of element. fmtname  Friendly name of element. [in,out]  th  Pointer to pointer containing address of head of list (will initialise if NULL) [in,out]  tc  Pointer to pointer containing address of last element on list (will set to last element). value  The value to set the element to. Returns: 0 on error (*th and *tc will remain unchanged)

int fdbfs_field_add_string (  const char *  name, const char *  fmtname, fields_t **  th, fields_t **  tc, char *  value )

Add string element to fields_t list. Parameters: name  Name of element. fmtname  Friendly name of element. [in,out]  th  Pointer to pointer containing address of head of list (will initialise if NULL) [in,out]  tc  Pointer to pointer containing address of last element on list (will set to last element). value  The value to set the element to. (not copied) Returns: 0 on error (*th and *tc will remain unchanged)

int fdbfs_field_append (  const char *  name, const char *  fmtname, fields_t **  th, fields_t **  tc, enum DataType  type, void *  value, size_t  len )

Appends field to a field list. It is recommended to use the fdbfs_field_int()/string()/whatever functions. This is mostly for internal use. Parameters: name  Name of field. fmtname  Alias of field. [in,out]  th  Pointer to pointer to head of field list. Will be initialised if (*th == NULL). [in,out]  tc  Pointer to pointer to last element in list. Will be reset. type  Datatype of field. value  Pointer to data to set to. len  Size of data.

fields_t* fdbfs_fields_from_dsp (  fdbfs_t *  f, const char *  tsp )

Parse defspec and create fields_t list from it. Parameters: f  Fakedbfs instance to operate on. tsp  Defspec to parse. Returns: fields_t list from defspec, or NULL on error.

int fdbfs_fields_set_mime (  const char *  mimetype, fields_t **  th, fields_t **  tc )

Sets the MIME type of a fields list. Sets the MIME type. Will remove any previously-existing mime fields. Parameters: mimetype  The mimetype to set to. [in,out]  Pointer  to pointer to head of list. [in,out]  Pointer  to pointer to last element of list. Returns: 0 on error.

fields_t* fdbfs_find_field_by_ehead (  fields_t *  h, struct EnumHead *  e )

Search for fields_t in a list by enumhead. Parameters: h  List to traverse. e  EnumHead to search for. Returns: fields_t that matches, or NULL if not found.

fields_t* fdbfs_find_field_by_ename (  fields_t *  h, const char *  e )

Search for fields_t in a list by enumhead name. Parameters: h  List to traverse. e  EnumHead name to search for. Returns: fields_t that matches, or NULL if not found.

fields_t* fdbfs_find_field_by_name (  fields_t *  h, const char *  name )

Search for fields_t in a list by name. Parameters: h  List to traverse. name  Name to search for. Returns: fields_t that matches, or NULL if not found.

fields_t* fdbfs_find_field_by_next (  fields_t *  h, fields_t *  next )

Searches for a field by its next member. Parameters: h  Head of list to search. next  Value to search for. Returns: Element found or NULL on not found.

void fdbfs_free_answer_t (  answer_t *  e  )

Free answer_t object. Parameters: e  Object to free.

fields_t* fdbfs_free_field (  fields_t *  e  )

Free fields_t object. If e->flags has the FIELDS_FLAG_MMAPED bit set, it will be munmap()ed, but only if HAVE_MMAP was defined at compile time. Parameters: e  fields_t object to free. Returns: Next element, or NULL on error.

void fdbfs_free_field_list (  fields_t *  h  )

Free list of fields_t's. Parameters: h  Head of list to traverse and free.
