17 /* SYNOPSIS */
18 FILE * stream,
19 const fpos_t * pos)
21 /* FUNCTION
22 Change the current position in a stream. This function is eqivalent
23 to fseek() with whence set to SEEK_SET. However, on some systems
24 fpos_t may be a complex structure, so this routine may be the only
25 way to portably reposition a stream.
27 INPUTS
28 stream - Modify this stream
29 pos - The new position in the stream.
31 RESULT
32 0 on success and -1 on error. If an error occurred, the global
33 variable errno is set.
