get_endianness (3) Linux Manual Page
NAME
get_endianness — report the byte sex of fields in a dirfile
SYNOPSIS
#include <getdata.h>
-
unsigned long get_endianness(DIRFILE *dirfile, intfragment_index);
DESCRIPTION
get_endianness() function queries a dirfile(5) database specified by dirfile and returns the byte sex for the fragment indexed by fragment_index. The byte sex of a fragment indicate the endianness of data stored in binary files associated with RAW fields defined in the specified fragment. The endianness of a fragment containing no RAW fields is ignored.
The dirfile argument must point to a valid DIRFILE object previously created by a call to dirfile_open(3).
RETURN VALUE
Upon successful completion, get_endianness() returns the byte sex of the specified fragment, which will be either GD_BIG_ENDIAN or GD_LITTLE_ENDIAN. On error, it returns zero and sets the dirfile error to a non-zero error value. Possible error values are:
GD_E_BAD_DIRFILE- The supplied dirfile was invalid.
GD_E_BAD_INDEX- The supplied index was out of range. The dirfile error may be retrieved by calling
get_error(3). A descriptive error string for the last error encountered can be obtained from a call toget_error_string(3).
