__getmainargs, __wgetmainargs

  • Artigo

Invokes command-line parsing and copies the arguments to main() back through the passed pointers.

int __getmainargs(
    int * _Argc, 
   char *** _Argv, 
   char *** _Env, 
   int _DoWildCard,
_startupinfo * _StartInfo);

 int __wgetmainargs (
   int *_Argc,
   wchar_t ***_Argv,
   wchar_t ***_Env,
   int _DoWildCard,
   _startupinfo * _StartInfo)

Parameters

  • _Argc
    An integer that contains the number of arguments that follow in argv. The argc parameter is always greater than or equal to 1.

  • _Argv
    An array of null-terminated strings representing command-line arguments entered by the user of the program. By convention, argv[0] is the command with which the program is invoked, argv[1] is the first command-line argument, and so on, until argv[argc], which is always NULL. The first command-line argument is always argv[1] and the last one is argv[argc – 1].

  • _Env
    An array of strings that represent the variables set in the user's environment. This array is terminated by a NULL entry.

  • _DoWildCard
    An integer that if set to 1 expands the wildcards in the command line arguments, or if set to 0 does nothing.

  • _StartInfo
    Other information to be passed to the CRT DLL.

Return Value

0 if successful; a negative value if unsuccessful.

Remarks

Use __getmainargs on non-wide character platforms, and __wgetmainargs on wide-character (Unicode) platforms.
