SYNOPSIS
|
2000-02-18 03:39:52 +08:00
|
|
|
#include <stdio.h>
|
|
|
|
int fsetpos(FILE *<[fp]>, const fpos_t *<[pos]>);
|
2008-11-01 05:08:03 +08:00
|
|
|
int _fsetpos_r(struct _reent *<[ptr]>, FILE *<[fp]>,
|
2003-08-23 02:52:25 +08:00
|
|
|
const fpos_t *<[pos]>);

DESCRIPTION
|
|
|
|
Objects of type <<FILE>> can have a ``position'' that records how much
|
|
|
|
of the file your program has already read. Many of the <<stdio>> functions
|
|
|
|
depend on this position, and many change it as a side effect.
|
|
|
|
|
|
|
|
You can use <<fsetpos>> to return the file identified by <[fp]> to a previous
|
|
|
|
position <<*<[pos]>>> (after first recording it with <<fgetpos>>).
|
|
|
|
|
|
|
|
See <<fseek>> for a similar facility.
|
|
|
|
|
|
|
|
RETURNS
|
|
|
|
<<fgetpos>> returns <<0>> when successful. If <<fgetpos>> fails, the
|
|
|
|
result is <<1>>. The reason for failure is indicated in <<errno>>:
|
|
|
|
either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
|
|
|
|
repositioning) or <<EINVAL>> (invalid file position).
|
|
|
|
|
|
|
|
PORTABILITY
|
|
|
|
ANSI C requires <<fsetpos>>, but does not specify the nature of
|
|
|
|
<<*<[pos]>>> beyond identifying it as written by <<fgetpos>>.
|
|
|
|
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
