+@PURPOSE@ Format a pattern into a string according to a format specifier
+@DESC@
+
+Converts the given pattern into text format described by the format specifier.
+The format specifier is similar to a C style printf string, which the
+printf(2) man page provides a good introduction to. However, as fontconfig
+already knows the type of data that is being printed, you must omit the type
+specifier. In its place put the element name you wish to print enclosed in
+curly braces ({}). For example, to print the family name and style the
+pattern, use the format "%{family} %{style}\n".
+There can be an option width specifier after the percent sign and before
+the opening brace. The width modifier acts similar to those in printf.
+The return value refers to newly allocated memory which should be freed by the
+caller using free(), or NULL if <parameter>format</parameter> is invalid.
