rewind (original) (raw)

[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.

The call:

rewind(stream)

shall be equivalent to:

(void) fseek(stream, 0L, SEEK_SET)

except that rewind() shall also clear the error indicator.

[CX] Since 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.
