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.
The following sections are informative.
APPLICATION USAGE None.
FUTURE DIRECTIONS None.
