FGETPOS(3) Library Functions Manual FGETPOS(3)

fgetpos — get current file position information

#include <stdio.h>

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

The fgetpos() function stores the current value of the 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(3) for repositioning the stream to its position at the time of the call to fgetpos() .

Upon successful completion, fgetpos() returns 0. Otherwise, it returns a non-zero value and sets errno to indicate the error.

The fgetpos() function will fail if:

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

The function may fail if:

The file descriptor underlying stream is not valid.
The file descriptor underlying stream is associated with a pipe or FIFO.
