NAME

       gd_endianness -- report the byte sex of fields in a dirfile

SYNOPSIS

       #include <getdata.h>

       unsigned long gd_endianness(DIRFILE *dirfile, int fragment_index);

DESCRIPTION

       The  gd_endianness() function queries a dirfile(5) database specified by dirfile and returns the byte sex for the fragment indexed by frag-
       ment_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 not meaningful.

       The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3).

RETURN VALUE

       Upon  successful  completion, gd_endianness() returns the byte sex of the specified fragment, which will be either GD_BIG_ENDIAN or GD_LIT-
       TLE_ENDIAN, bitwise-or'd with either GD_ARM_ENDIAN or GD_NOT_ARM_ENDIAN, indicating whether double-precision floating point  data  in  this
       fragment  are  stored in the old ARM middle-endian format.  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 gd_error(3).  A descriptive error string for the last error encountered can be obtained  from
       a call to gd_error_string(3).
