When no glyph is 35778556Sobrien * available, it uses glyph 0, which is normally equal to U+FFFD. 35878556Sobrien */ 35978556Sobrien 36078556Sobrienstruct vt_font_map { 36178556Sobrien uint32_t vfm_src; 36278556Sobrien uint16_t vfm_dst; 36378556Sobrien uint16_t vfm_len; 36478556Sobrien}; 36578556Sobrien 36678556Sobrienstruct vt_font { 36778556Sobrien struct vt_font_map *vf_bold; 36878556Sobrien struct vt_font_map *vf_normal; 36978556Sobrien uint8_t *vf_bytes; 37078556Sobrien unsigned int vf_height, vf_width, 37178556Sobrien vf_normal_length, vf_bold_length; 37278556Sobrien unsigned int vf_refcount; 37378556Sobrien}; 37478556Sobrien 37578556Sobrienstruct mouse_cursor { 37678556Sobrien uint8_t map[64 * 64 / 8]; 37778556Sobrien uint8_t mask[64 * 64 / 8]; 37878556Sobrien uint8_t w; 37978556Sobrien uint8_t h; 38078556Sobrien}; 38178556Sobrien 38278556Sobrienconst uint8_t *vtfont_lookup(const struct vt_font *vf, term_char_t c); 38378556Sobrienstruct vt_font *vtfont_ref(struct vt_font *vf); 38478556Sobrienvoid vtfont_unref(struct vt_font *vf); 38578556Sobrienint vtfont_load(vfnt_t *f, struct vt_font **ret); 38678556Sobrien 38778556Sobrien/* Sysmouse. */ 38878556Sobrienvoid sysmouse_process_event(mouse_info_t *mi); 38978556Sobrienvoid vt_mouse_event(int type, int x, int y, int event, int cnt); 39078556Sobrien 39178556Sobrien#endif /* !_DEV_VT_VT_H_ */ 39278556Sobrien
