.SH NAME
fnqualify \- qualify a filename
.SH SYNOPSIS
.nf
#include <publib.h>
.sp 1
size_t \fBfnqualify\fR(char *\fIresult\fR, const char *\fIpath\fR, size_t \fImax\fR);
.SH "DESCRIPTION"
\fIfname_qualify\fR 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 \fBfoo\fR, not \fB/tmp/foo\fR), 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.
.PP
Simplifications like replacing /./ with /, and /foo/../bar with /bar
are not done because of problems with symbolic links.
.SH 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.
