.SH "DESCRIPTION"
|
|
.PP
|
|
Builds a pattern using a list of objects, types and values. Each
|
|
value to be entered in the pattern is specified with three arguments:
|
|
.IP 1.
|
|
Object name, a string describing the property to be added.
|
|
.IP 2.
|
|
Object type, one of the FcType enumerated values
|
|
.IP 3.
|
|
Value, not an FcValue, but the raw type as passed to any of the
|
|
FcPatternAdd<type> functions. Must match the type of the second
|
|
argument.
|
|
.PP
|
|
The argument list is terminated by a null object name, no object type nor
|
|
value need be passed for this. The values are added to `pattern', if
|
|
`pattern' is null, a new pattern is created. In either case, the pattern is
|
|
returned. Example
|
|
.PP
|
|
.sp
|
|
.nf
|
|
pattern = FcPatternBuild (0, FC_FAMILY, FcTypeString, "Times", (char *) 0);
|
|
.sp
|
|
.fi
|
|
.PP
|
|
FcPatternVaBuild is used when the arguments are already in the form of a
|
|
varargs value. FcPatternVapBuild is a macro version of FcPatternVaBuild
|
|
which returns its result directly in the \fIresult\fR
|
|
variable.
