Many of the <<stdio>> functions -depend on this position, and many change it as a side effect. - -You can use <<fgetpos>> to report on the current position for a file -identified by <[fp]>; <<fgetpos>> will write a value -representing that position at <<*<[pos]>>>. Later, you can -use this value with <<fsetpos>> to return the file to this -position. - -In the current implementation, <<fgetpos>> simply uses a character -count to represent the file position; this is the same number that -would be returned by <<ftell>>. - -RETURNS -<<fgetpos>> returns <<0>> when successful. If <<fgetpos>> fails, the -result is <<1>>. Failure occurs on streams that do not support -positioning; the global <<errno>> indicates this condition with the -value <<ESPIPE>>. - -PORTABILITY -<<fgetpos>> is required by the ANSI C standard, but the meaning of the -value it records is not specified beyond requiring that it be -acceptable as an argument to <<fsetpos>>. In particular, other -conforming C implementations may return a different result from -<<ftell>> than what <<fgetpos>> writes at <<*<[pos]>>>. - -No supporting OS subroutines are required. -*/ - -#include <_ansi.h> -#include <reent.h> -#include <stdio.h> - -int -_DEFUN(_fgetpos_r, (ptr, fp, pos), - struct _reent * ptr _AND - FILE * fp _AND - _fpos_t * pos) -{ - *pos = _ftell_r (ptr, fp); - - if (*pos != -1) - { - return 0; - } - return 1; -} - -#ifndef _REENT_ONLY - -int -_DEFUN(fgetpos, (fp, pos), - FILE * fp _AND - _fpos_t * pos) -{ - return _fgetpos_r (_REENT, fp, pos); -} - -#endif /* !_REENT_ONLY */ |
