.SH "DESCRIPTION"
|
|
.PP
|
|
Adds all chars in \fIb\fR to \fIa\fR\&.
|
|
In other words, this is an in-place version of FcCharSetUnion.
|
|
If \fIchanged\fR is not NULL, then it returns whether any new
|
|
chars from \fIb\fR were added to \fIa\fR\&.
|
|
Returns FcFalse on failure, either when \fIa\fR is a constant
|
|
set or from running out of memory.
