_pgmptr, _wpgmptr

The path of the executable file. Deprecated; use _get_pgmptr and _get_wpgmptr.

Syntax

extern char *_pgmptr;
extern wchar_t *_wpgmptr;

Remarks

When a program is run from the command interpreter (Cmd.exe), _pgmptr is automatically initialized to the full path of the executable file. For example, if Hello.exe is in C:\BIN and C:\BIN is in the path, _pgmptr is set to C:\BIN\Hello.exe when you execute:

C> hello

When a program isn't run from the command line, _pgmptr might be initialized to the program name (the file's base name without the file name extension) or to a file name, relative path, or full path.

_wpgmptr is the wide-character counterpart of _pgmptr for use with programs that use wmain.

Generic-text routine mappings

Tchar.h routine	_UNICODE and _MBCS not defined	_MBCS defined	_UNICODE defined
_tpgmptr	_pgmptr	_pgmptr	_wpgmptr

Requirements

Variable	Required header
_pgmptr, _wpgmptr	<stdlib.h>

Example

The following program demonstrates the use of _pgmptr.

// crt_pgmptr.c
// compile with: /W3
// The following program demonstrates the use of _pgmptr.
//
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
   printf("The full path of the executing program is : %Fs\n",
     _pgmptr); // C4996
   // Note: _pgmptr is deprecated; use _get_pgmptr instead
}

You could use _wpgmptr by changing %Fs to %S and main to wmain.
