_getpid_r—Reentrant version of getpidSynopsis
#include <reent.h> int _getpid_r(struct _reent *ptr);
Description
This is a reentrant version of getpid. It
takes a pointer to the global data block, which holds
errno.
We never need errno, of course, but for consistency we
still must have the reentrant pointer argument.
