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(3C) 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 may
fail if: The file descriptor underlying stream is not valid. The
file descriptor underlying stream is associated with a pipe, a
FIFO, or a socket. The current value of the file position cannot
be represented correctly in an object of type fpos_t. The
fgetpos() function has a transitional interface for 64-bit file
offsets. See lf64(5). See a
