_get_wpgmptr

Gets the current value of the _wpgmptr global variable.

Syntax

errno_t _get_wpgmptr(
   wchar_t **pValue
);

Parameters

pValue
A pointer to a string to be filled with the current value of the _wpgmptr variable.

Return value

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.

Remarks

Only call _get_wpgmptr if your program has a wide entry point, like wmain() or wWinMain(). The _wpgmptr global variable contains the full path to the executable associated with the process as a wide-character string. For more information, see _pgmptr, _wpgmptr.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.

Requirements

Routine Required header
_get_wpgmptr <stdlib.h>
