_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.
