Command-line arguments available to other functions?

In C, is there any way to make command line arguments available to other functions without passing them as arguments to the functions?

Some compilers provides global _argc and _argv variables for that exact purpose. Or use platform-specific APIs, like GetCommandLine() and CommandLineToArgvW() on Windows.

As DaoWen has said, the command-line arguments are just data, available in main(). So if you don't want to pass a command-line argument as a parameter to another function but you want it available in other functions, you could strcpy()/strncpy() the string into a global string.
