libc.a reference
__crt0_glob_function
Syntax
| | #include <crt0.h>
char **__crt0_glob_function(char *_argument);
|
Description
If the application wishes to provide a wildcard expansion function, it
should define a __crt0_glob_function function. It should return
a list of the expanded values, or 0 if no expansion will occur. The
startup code will free the returned pointer if it is nonzero.
If no expander function is provided, wildcards will be expanded in the
POSIX.1 style by the default __crt0_glob_function from the C
library. To disable expansion, provide a __crt0_glob_function
that always returns 0.
