__getmainargs, __wgetmainargs

  • Artikkeli

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

Syntax

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.
