DESCRIPTION

51       Creates a cursor from a font glyph. X provides a set of standard cursor
52       shapes in a special font named cursor. Applications are encouraged to
53       use this interface for their cursors because the font can be customized
54       for the individual display type.
55
56       All pixels which are set to 1 in the source will use the foreground
57       color (as specified by fore_red, fore_green and fore_blue). All pixels
58       set to 0 will use the background color (as specified by back_red,
59       back_green and back_blue).
60

RETURN VALUE

62       Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the
63       event loop.
64
65       If you want to handle errors directly with xcb_request_check instead,
66       use xcb_create_glyph_cursor_checked. See xcb-requests(3) for details.
67

ERRORS

69       xcb_alloc_error_t
70                 The X server could not allocate the requested resources (no
71                 memory?).
72
73       xcb_font_error_t
74                 The specified source_font or mask_font does not exist.
75
76       xcb_value_error_t
77                 Either source_char or mask_char are not defined in
78                 source_font or mask_font, respectively.
