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.
