XFreeFont()XFreeFont()NameXFreeFont – unload a font and free storage for the font structure.
Synopsis
XFreeFont(display, font_struct)
Display *display;
XFontStruct *font_struct;
Arguments
display Specifies a connection to an X server; returned from
XOpenDisplay().
font_struct
Specifies the storage associated with the font.
DescriptionXFreeFont() frees the memory allocated for the font_struct font infor‐
mation structure (XFontStruct) filled by XQueryFont() or XLoadQuery‐
Font(). XFreeFont() frees all storage associated with the font_struct
argument. Neither the data nor the font should be referenced again.
The server unloads and frees the font itself if no other client has
loaded it.

Text.
