rewind - reset file position indicator in a stream
#include <stdio.h> void rewind(FILE *stream);
The call:is equivalent to:rewind(stream)
(void) fseek(stream, 0L, SEEK_SET)
except that rewind() also clears the error indicator.
The rewind() function returns no value.
Refer to fseek() with the exception of [EINVAL] which does not apply.
None.
Because rewind() does not return a value, an application wishing to detect errors should clear errno, then call rewind(), and if errno is non-zero, assume an error has occurred.
None.
fseek(), <stdio.h>.
