XmFontListAdd creates a new font list consisting of the contents of
the oldlist and the new font-list element being added. This
function deallocates the oldlist after extracting the required
information; therefore, do not reference oldlist thereafter.
NOTE:
This function is obsolete and exists for compatibility
with previous releases. It has been replaced by XmFontListAppendEntry.
oldlist
Specifies a pointer to the font list to which an entry will be added.
font
Specifies a pointer to a font structure for which the new font list is
generated. This is the structure returned by the XLib XLoadQueryFont
function.
charset
Specifies the character set identifier for the font.
This can be XmSTRING_DEFAULT_CHARSET, but this value does not
comply with the AES, and it may be removed in future versions of Motif.
If the value is XmSTRING_DEFAULT_CHARSET, the routine derives the
character set from the current language environment.
Return values
Returns NULL if oldlist is NULL; returns oldlist if
font or charset is NULL; otherwise, returns a new font list.
