gd_raw_filename — retrieve the pathname of a binary file in a Dirfile
#include <getdata.h> char *gd_raw_filename(DIRFILE *dirfile, const char *field_code);
The gd_raw_filename() function reports the pathname of the file backing the RAW field specified by field_code in the dirfile specified by dirfile. If field_code contains a valid representation suffix, it will be ignored.
On success, gd_raw_filename() returns the full pathname of the binary file associated with the specified field in a newly-allocated buffer. By default, this buffer is allocated with malloc(3), but a different memory manager may be specified by calling gd_alloc_funcs(3) before calling this function. The caller is responsible for deallocating the returned buffer. On error, this function returns NULL and stores a negative-valued error code in the DIRFILE object which may be retrieved by a subsequent call to gd_error(3). Possible error codes are: GD_E_ALLOC The library was unable to allocate memory. GD_E_BAD_CODE The field specified by field_code was not found. GD_E_BAD_DIRFILE The supplied dirfile was invalid. GD_E_BAD_FIELD_TYPE The field specified by field_code was not a RAW field. GD_E_UNKNOWN_ENCODING The encoding scheme of the specified field could not be determined or was not understood by GetData. A descriptive error string for the error may be obtained by calling gd_error_string(3).
The get_raw_filename() function appeared in GetData-0.4.2. Memory for the string it returned was managed by GetData. In GetData-0.7.0, this function was renamed to gd_raw_filename(). In GetData-0.8.0, the returned string changed to a malloc'd buffer, and the responsibility for freeing the buffer passed to the caller.
