#include <publib.h>
size_t fnqualify(char *result, const char *path, size_t max);
 "DESCRIPTION"
fname_qualify qualifies a filename. This means that if the
input name is not an absolute name (i.e. starts from the root
directory, e.g. is foo, not /tmp/foo), the current
directory will be prepended to it. Also, tilde conversion is done: if
the filename begins with a tilde (~), the tilde is replaced with the
home directory of the user, and if it begins with a tilde and a
username, both are replaced with the home directory of the given user.

Simplifications like replacing /./ with /, and /foo/../bar with /bar
are not done because of problems with symbolic links.
 RETURNS
The function returns -1 if there was some error, or the total size of
the full name otherwise. The return value may be greater than the
maximum size given by the last argument; only as much as allowed by
that is actually written, though.
