NAME¶
FcPatternBuild, FcPatternVaBuild, FcPatternVapBuild - Create patterns from
arguments
SYNOPSIS¶
#include <fontconfig/fontconfig.h>
FcPattern * FcPatternBuild (FcPattern * pattern, ...);
FcPattern * FcPatternVaBuild (FcPattern * pattern, va_list va);
void FcPatternVapBuild (FcPattern * result, FcPattern *pattern, va_list va);
DESCRIPTION¶
Builds a pattern using a list of objects, types and values. Each value to be
entered in the pattern is specified with three arguments:
- 1.
- Object name, a string describing the property to be added.
- 2.
- Object type, one of the FcType enumerated values
- 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.
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
pattern = FcPatternBuild (0, FC_FAMILY, FcTypeString, "Times", (char *) 0);
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
result variable.
