NAME
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.
