_get_pgmptr
Gets the current value of the _pgmptr global variable.
Syntax
errno_t _get_pgmptr(
char **pValue
);
Parameters
pValue
A pointer to a string to be filled with the current value of the _pgmptr 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_pgmptr if your program has a narrow entry point, like main() or WinMain(). The _pgmptr global variable contains the full path to the executable associated with the process. 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.
