Getting argv[0] in PBCC

[Adam J. Drake]

Try this:

#COMPILE EXE
#DIM ALL

#INCLUDE "WIN32API.INC"

DECLARE FUNCTION AppPath() AS STRING

FUNCTION PBMAIN () AS LONG

    PRINT AppPath()
    WAITKEY$

END FUNCTION

FUNCTION AppPath() AS STRING
    
    LOCAL sRet          AS STRING
    LOCAL lpFileName    AS ASCIIZ * %MAX_PATH
    LOCAL nSize         AS DWORD
    LOCAL hModule       AS DWORD
    LOCAL dwLen         AS DWORD
    
    hModule = GetModuleHandle(BYVAL %NULL)
    nSize = %MAX_PATH
    dwLen = GetModuleFileName(hModule, lpFileName, nSize)
    
    IF dwLen <> 0 THEN
        sRet = MID$(lpFileName, 1, INSTR(-1, lpFileName, "\"))
    END IF
    
    FUNCTION = sRet
    
END FUNCTION

The API looks to be the more reliable way for my purposes.

I already know my program will be called by a .bat which will be called by Windows Scheduler. The .exe would be called from an absolute path to be sure it is found without having to add its directory to the PATH. Therefore, CURDIR$ will not necessarily return where the .exe is located. I want to guarantee that my log files will be in the same place as the .exe without assuming anything about where the user might have put the .exe.

Curdir$ in PowerBASIC

or in Api

GetCurrentDirectory
The GetCurrentDirectory function retrieves the current directory for the current process. 

DWORD GetCurrentDirectory(
  DWORD nBufferLength,  // size, in characters, of directory buffer
  LPTSTR lpBuffer       // pointer to buffer for current directory
);
 
Parameters

nBufferLength 

Specifies the length, in characters, of the buffer for the current directory string. The buffer length must include room for a terminating null character. 

lpBuffer
 
Pointer to the buffer for the current directory string. This null-terminated string specifies the absolute path to the current directory. 

Return Values

If the function succeeds, the return value specifies the number of characters written to the buffer, not including the terminating null character. 

If the function fails, the return value is zero. To get extended error information, call GetLastError. 

If the buffer pointed to by lpBuffer is not large enough, the return value specifies the required size of the buffer, including the number of bytes necessary for a terminating null character.

I actually don't even need the .exe's name, just the full path of the directory that the .exe is in. How do I get this in PBCC4.03?
