_pgmptr, _wpgmptr
The path of the executable file. Deprecated; use _get_pgmptr and _get_wpgmptr.
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 is not 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.

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.
