- - '*' characters may get expanded or lead to a failure with error code
- ERROR_PATH_NOT_FOUND.
+ - '*', '?' characters may get expanded through wildcard expansion in the
+ callee: By default, in the callee, the initialization code before main()
+ takes the result of GetCommandLine(), wildcard-expands it, and passes it
+ to main(). The exceptions to this rule are:
+ - programs that inspect GetCommandLine() and ignore argv,
+ - mingw programs that have a global variable 'int _CRT_glob = 0;',
+ - Cygwin programs, when invoked from a Cygwin program.
