FGETPOS(3C) Standard C Library Functions FGETPOS(3C)
fgetpos - get current file position information
#include <stdio.h>
int fgetpos(FILE *stream, fpos_t *pos);
The fgetpos() function stores the current value of the file position
indicator for the stream pointed to by stream in the object pointed
to by pos. The value stored contains unspecified information usable
by fsetpos(3C) for repositioning the stream to its position at the
time of the call to fgetpos().
Upon successful completion, fgetpos() returns 0. Otherwise, it
returns a non-zero value and sets errno to indicate the error.
The fgetpos() function may fail if:
EBADF
The file descriptor underlying stream is not valid.
ESPIPE
The file descriptor underlying stream is associated with
a pipe, a FIFO, or a socket.
EOVERFLOW
The current value of the file position cannot be
represented correctly in an object of type fpos_t.
The fgetpos() function has a transitional interface for 64-bit file
offsets. See lf64(7).

NAME
fgetpos - get current file position information
SYNOPSIS
#include <stdio.h>
int fgetpos(FILE *stream, fpos_t *pos);
DESCRIPTION
The fgetpos() function stores the current value of the file position
indicator for the stream pointed to by stream in the object pointed
to by pos. The value stored contains unspecified information usable
by fsetpos(3C) for repositioning the stream to its position at the
time of the call to fgetpos().
RETURN VALUES
Upon successful completion, fgetpos() returns 0. Otherwise, it
returns a non-zero value and sets errno to indicate the error.
ERRORS
The fgetpos() function may fail if:
EBADF
The file descriptor underlying stream is not valid.
ESPIPE
The file descriptor underlying stream is associated with
a pipe, a FIFO, or a socket.
EOVERFLOW
The current value of the file position cannot be
represented correctly in an object of type fpos_t.
USAGE
The fgetpos() function has a transitional interface for 64-bit file
offsets. See lf64(7).
