PROLOG

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

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.

NAME

       ftell, ftello - return a file offset in a stream

SYNOPSIS

       #include <stdio.h>

       long ftell(FILE *stream);

       off_t ftello(FILE *stream);

DESCRIPTION

       The ftell() function shall obtain the current value of the file-position indicator for the stream pointed to by stream.

       The ftello() function shall be equivalent to ftell(), except that the return value is of type off_t.

RETURN VALUE

       Upon successful completion, ftell()  and ftello()  shall return the current value of the file-position indicator for the stream measured in
       bytes from the beginning of the file.

       Otherwise, ftell()  and ftello()  shall return -1, cast to long and off_t respectively, and set errno to indicate the error.

ERRORS

       The ftell()  and ftello()  functions shall fail if:

       EBADF  The file descriptor underlying stream is not an open file descriptor.

       EOVERFLOW
	      For ftell(), the current file offset cannot be represented correctly in an object of type long.

       EOVERFLOW
	      For ftello(), the current file offset cannot be represented correctly in an object of type off_t.

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

       The ftell() function may fail if:

       ESPIPE The file descriptor underlying stream is associated with a socket.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE
