16.2 How to disable filename wildcards expansion

Q: I don't want my program to glob its arguments (they aren't files at all, but they include characters like * and ?). What should I do?

A: You have these alternatives:

• Surround your arguments with single or double quotes (this is what you would do under a Unix shell).
• Disable globbing for your program by linking it with your custom version of the function with the special name __crt0_glob_function and make it always return a NULL pointer. See the documentation of this function in the library reference, for more details. Here's an example:

   #include <crt0.h>
  
   char **__crt0_glob_function (char *arg)
   {
     return 0;
   }
