.SH SYNOPSIS

.nf
\f[C]
#include <allegro5/allegro.h>

bool al_ustr_next(const ALLEGRO_USTR *us, int *pos)
\f[R]
.fi
.SH DESCRIPTION
.PP
Find the byte offset of the next code point in string, beginning at
\f[V]*pos\f[R].
\f[V]*pos\f[R] does not have to be at the beginning of a code point.
.PP
Returns true on success, and the value pointed to by \f[V]pos\f[R] will
be updated to the found offset.
Otherwise returns false if \f[V]*pos\f[R] was already at the end of the
string, and \f[V]*pos\f[R] is unmodified.
.PP
This function just looks for an appropriate byte; it doesn\[cq]t check
if found offset is the beginning of a valid code point.
If you are working with possibly invalid UTF-8 strings then it could
skip over some invalid bytes.
