Description

This routine compares one thread identifier to another thread identifier. (This routine does not check whether the objects that correspond to the identifiers currently exist.) If the identifiers have values indicating that they designate the same object, 1 (true) is returned. If the values do not designate the same object, 0 (false) is returned.

This routine is implemented as a C macro.

Return Values

Possible return values are as follows:
