rewind - reset file position indicator to start of stream

Syntax	#include <stdio.h> void rewind(FILE *stream);
Description	The call rewind(stream) is equivalent to: (void) fseek(stream, 0L, SEEK_SET) except that rewind() also clears the error indicator for stream.
Errors Notes	See fseek() - with the exception of EINVAL. Since rewind() does not return a value, an application wishing to detect errors should first set errno to 0, then call rewind(), and if errno is non-zero, assume that an error has occurred. The program environment determines whether rewind() is executed for a BS2000 or POSIX file. BS2000 rewind() can also be used without changes for files with record I/O. (End)
