DESCRIPTION
The
XListFonts
function returns an array of available font names
(as controlled by the font search path; see
XSetFontPath)
that match the string you passed to the pattern argument.
The pattern string can contain any characters,
but each asterisk (*) is a wildcard for any number of characters,
and each question mark (?) is a wildcard for a single character.
If the pattern string is not in the Host Portable Character Encoding
the result is implementation dependent.
Use of uppercase or lowercase does not matter.
Each returned string is null-terminated.
If the data returned by the server is in the Latin Portable Character Encoding,
then the returned strings are in the Host Portable Character Encoding.
Otherwise, the result is implementation dependent.
If there are no matching font names,
XListFonts
returns NULL.
The client should call
XFreeFontNames
when finished with the result to free the memory.
The
XFreeFontNames
function frees the array and strings returned by
XListFonts
or
XListFontsWithInfo.
The
XListFontsWithInfo
function returns a list of font names that match the specified pattern and their
associated font information.
The list of names is limited to size specified by maxnames.
The information returned for each font is identical to what
XLoadQueryFont
would return except that the per-character metrics are not returned.
The pattern string can contain any characters,
but each asterisk (*) is a wildcard for any number of characters,
and each question mark (?) is a wildcard for a single character.
If the pattern string is not in the Host Portable Character Encoding
the result is implementation dependent.
Use of uppercase or lowercase does not matter.
Each returned string is null-terminated.
If the data returned by the server is in the Latin Portable Character Encoding,
then the returned strings are in the Host Portable Character Encoding.
Otherwise, the result is implementation dependent.
If there are no matching font names,
XListFontsWithInfo
returns NULL.
To free only the allocated name array,
the client should call
XFreeFontNames.
To free both the name array and the font information array,
or to free just the font information array,
the client should call
XFreeFontInfo.
The
XFreeFontInfo
function frees the the font information array.
To free an
XFontStruct
structure without closing the font,
call
XFreeFontInfo
with the names argument specified as NULL.
