gd_raw_filename - Man Page

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.

Return Value

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:


The library was unable to allocate memory.


The field specified by field_code was not found.


The supplied dirfile was invalid.


The field specified by field_code was not a RAW field.


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.
