fgetpos - get current file position information
Návod, kniha: POSIX Programmer's Manual
#include <stdio.h>
int fgetpos(FILE *restrict
stream, fpos_t
*restrict pos);
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().
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:
- 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.
