Actually, according to "info libc alpha __crt0_glob_function", it must
be declared as char**. Of course, a regular int will work as well, but
it is a good idea to always define such functions to be exact duplicates
of their library equivalents, just to be safe. For example, when I
don't care about or wish to disable globbing, I use this definition:
/* disable command-line globbing */
char **__crt0_glob_function( char *_argument )
{
return NULL;
}
This is 100% guaranteed to work, unless the libc definition itself
changes. The key thing is that your function, no matter what you define
it as, must return a zero, or the startup code will go haywire. This,
to me, is clearly explained by the libc reference, and the FAQ clearly
states to look up the libc reference for more information. Seems simple
enough to me...
Oh, and I believe that the section that mentions the crt0 functions has
not been changed since the original v2 FAQ. Of course, you should
always make sure to have the newest version. ;)
