Gd_raw_filename retrieve the pathname of a binary file in a dirfile
#include <getdata.h> const char *gd_raw_filename(DIRFILE *dirfile, const char *field_code);
The gd_raw_filename() function retrieves 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. On error, NULL is returned and the dirfile error is set to a non-zero error value. Possible error values 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_BAD_REPR
The representation suffix specified in field_code was not recognised.
GD_E_UNKNOWN_ENCODING
The encoding scheme of the specified field could not be determined or was not understood by GetData.
The dirfile error may be retrieved by calling gd_error(3). A descriptive error string for the last error encountered can be obtained from a call to gd_error_string(3).
