NAME
fgetpos - get current file position information
SYNOPSIS
#include <stdio.h>
int fgetpos(FILE *restrict stream, fpos_t *restrict pos);
DESCRIPTION
The fgetpos() function shall store the current values of the parse
state (if any) and 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() for repositioning the
stream to its position at the time of the call to fgetpos().
RETURN VALUE
Upon successful completion, fgetpos() shall return 0; otherwise, it
shall return a non-zero value and set errno to indicate the error.
ERRORS
The fgetpos() function shall fail if:
EOVERFLOW
The current value of the file position cannot be represented
correctly in an object of type fpos_t.
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,
FIFO, or socket.
