gd_frameoffset64(3)						      GETDATA						       gd_frameoffset64(3)

NAME
gd_frameoffset64, gd_alter_frameoffset64 -- report or change the frame offset of fields in a dirfile, with largefile support SYNOPSIS
#define _LARGEFILE64_SOURCE #include <getdata.h> off64_t gd_frameoffset(DIRFILE *dirfile, int fragment_index); int gd_alter_frameoffset64(DIRFILE *dirfile, off64_t offset, int fragment_index, int move); DESCRIPTION
These version of gd_frameoffset(3) and gd_alter_frameoffset(3) use a 64-bit offset type, even if off_t is a 32-bit type. They are only available if the caller defines _LARGEFILE64_SOURCE before including getdata.h. If off_t is a 64-bit type (i.e. if _FILE_OFFSET_BITS is defined to be 64), these function will be called gd_frameoffset() and gd_al- ter_frameoffset(). Otherwise, gd_frameoffset() and gd_alter_frameoffset() will be versions of these functions which use a 32-bit off_t. SEE ALSO
gd_alter_frameoffset(3), gd_frameoffset(3), feature_test_macros(7) Version 0.7.0 16 July 2010 gd_frameoffset64(3)
