| _rewind_r |
| |
| ANSI_SYNOPSIS |
| #include <stdio.h> |
| void rewind(FILE *<[fp]>); |
| void _rewind_r(struct _reent *<[ptr]>, FILE *<[fp]>); |
| |
| TRAD_SYNOPSIS |
| #include <stdio.h> |
| void rewind(<[fp]>) |
| FILE *<[fp]>; |
| |
| void _rewind_r(<[ptr]>, <[fp]>) |
| struct _reent *<[ptr]>; |
| FILE *<[fp]>; |
| |
| DESCRIPTION |
| <<rewind>> returns the file position indicator (if any) for the file |
| or stream identified by <[fp]> to the beginning of the file. It also |
| clears any error indicator and flushes any pending output. |
