get_framenum_subset64 — perform a reverse look-up on a monotonic dirfile field
Synopsis
#define _LARGEFILE64_SOURCE
#include <getdata.h>
- double get_framenum_subset64(DIRFILE *dirfile, const char *field_code, double value, off64_t field_start, off64_t field_end);
Description
This version of get_framenum_subset(3) uses a 64-bit offset type, even if off_t is a 32-bit type. It is only available if one defines _LARGEFILE64_SOURCE. If off_t is a 64-bit type (i.e. if _FILE_OFFSET_BITS is defined to be 64), this function will be called get_framenum_subset(). Otherwise, get_framenum_subset() will be a version of this function which uses a 32-bit off_t.
