FGETPOS(3P)		   POSIX Programmer's Manual		   FGETPOS(3P)

       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

       fgetpos — get current file position information

       #include <stdio.h>

       int fgetpos(FILE *restrict stream, fpos_t *restrict pos);

       The functionality described on this reference page is aligned with  the
       ISO C  standard.	 Any  conflict between the requirements described here
       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
       defers to the ISO C standard.

       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().

       The  fgetpos()  function	 shall not change the setting of errno if suc‐

       Upon successful completion, fgetpos() shall  return  0;	otherwise,  it
       shall return a non-zero value and set errno to indicate the error.

       The fgetpos() function shall fail if:

       EBADF  The file descriptor underlying stream is not valid.

	      The  current  value  of  the file position cannot be represented
	      correctly in an object of type fpos_t.

       ESPIPE The file descriptor underlying stream is associated with a pipe,
	      FIFO, or socket.
