Returns zero if successful; an error code on failure. If pValue is NULL, the invalid parameter handler is invoked as described in Parameter Validation. If execution is allowed to continue, this function sets errno to EINVAL and returns EINVAL.
The _wpgmptrglobal variable contains the full path to the executable associated with the process as a wide-character string. For more information, see _pgmptr, _wpgmptr.
