Roger,
I'm somewhat dubious about the utility of this capability. But if you
were to offer a patch, I would suggest we add a new function called
pj_find_lib() that returns the full path given a filename. Most of
pj_open_lib() would be migrated into that, and then pj_open_lib()
would use it.
I suppose if we are using fopen() to discover files, this will result
in an extra unnecessary file opening and closing which might suck. I
suppose pj_find_lib() could also return the file handle, and pj_open_lib
would become a very minimal wrapper around it to preserve the old api.
What I am not likely to accept is a change to the pj_open_lib() ABI.
Best regards,
