From dd7595a3475407a7fa96a97393bae8c5220e8762 Mon Sep 17 00:00:00 2001 From: David Walter Seikel Date: Wed, 4 Jan 2012 18:41:13 +1000 Subject: Add the base Enlightenment Foundation Libraries - eina, eet, evas, ecore, embryo, and edje. Note that embryo wont be used, but I'm not sure yet if you can build edje without it. --- .../ecore/src/lib/ecore_x/xcb/ecore_xcb_dpms.c | 318 +++++++++++++++++++++ 1 file changed, 318 insertions(+) create mode 100644 libraries/ecore/src/lib/ecore_x/xcb/ecore_xcb_dpms.c (limited to 'libraries/ecore/src/lib/ecore_x/xcb/ecore_xcb_dpms.c') diff --git a/libraries/ecore/src/lib/ecore_x/xcb/ecore_xcb_dpms.c b/libraries/ecore/src/lib/ecore_x/xcb/ecore_xcb_dpms.c new file mode 100644 index 0000000..63b7f1e --- /dev/null +++ b/libraries/ecore/src/lib/ecore_x/xcb/ecore_xcb_dpms.c @@ -0,0 +1,318 @@ +#include "ecore_xcb_private.h" +#ifdef ECORE_XCB_DAMAGE +# include +#endif + +/* local variables */ +static Eina_Bool _dpms_avail = EINA_FALSE; + +void +_ecore_xcb_dpms_init(void) +{ + LOGFN(__FILE__, __LINE__, __FUNCTION__); + +#ifdef ECORE_XCB_DPMS + xcb_prefetch_extension_data(_ecore_xcb_conn, &xcb_dpms_id); +#endif +} + +void +_ecore_xcb_dpms_finalize(void) +{ +#ifdef ECORE_XCB_DPMS + const xcb_query_extension_reply_t *ext_reply; +#endif + + LOGFN(__FILE__, __LINE__, __FUNCTION__); + +#ifdef ECORE_XCB_DPMS + ext_reply = xcb_get_extension_data(_ecore_xcb_conn, &xcb_dpms_id); + if ((ext_reply) && (ext_reply->present)) + { + xcb_dpms_get_version_cookie_t cookie; + xcb_dpms_get_version_reply_t *reply; + + cookie = + xcb_dpms_get_version_unchecked(_ecore_xcb_conn, + XCB_DPMS_MAJOR_VERSION, + XCB_DPMS_MINOR_VERSION); + reply = xcb_dpms_get_version_reply(_ecore_xcb_conn, cookie, NULL); + if (reply) + { + if (reply->server_major_version >= 1) + _dpms_avail = EINA_TRUE; + free(reply); + } + } +#endif +} + +/** + * @defgroup Ecore_X_DPMS_Group X DPMS Extension Functions + * + * Functions related to the X DPMS Extension + */ + +/** + * Checks if the DPMS extension is available or not. + * + * @return @c EINA_TRUE if the DPMS extension is available, + * @c EINA_FALSE otherwise. + * + * Return EINA_TRUE if the X server supports the DPMS Extension version 1.0, + * EINA_FALSE otherwise. + * + * @ingroup Ecore_X_DPMS_Group + */ +EAPI Eina_Bool +ecore_x_dpms_query(void) +{ +// LOGFN(__FILE__, __LINE__, __FUNCTION__); + + return _dpms_avail; +} + +/** + * Checks if the X server is capable of DPMS. + * @return @c 1 if the X server is capable of DPMS, @c 0 otherwise. + * @ingroup Ecore_X_DPMS_Group + */ +EAPI Eina_Bool +ecore_x_dpms_capable_get(void) +{ + Eina_Bool ret = EINA_FALSE; +#ifdef ECORE_XCB_DPMS + xcb_dpms_capable_cookie_t cookie; + xcb_dpms_capable_reply_t *reply; +#endif + + LOGFN(__FILE__, __LINE__, __FUNCTION__); + CHECK_XCB_CONN; + + if (!_dpms_avail) return EINA_FALSE; + +#ifdef ECORE_XCB_DPMS + cookie = xcb_dpms_capable_unchecked(_ecore_xcb_conn); + reply = xcb_dpms_capable_reply(_ecore_xcb_conn, cookie, NULL); + if (reply) + { + ret = reply->capable; + free(reply); + } +#endif + + return ret; +} + +/** + * Checks the DPMS state of the display. + * @return @c EINA_TRUE if DPMS is enabled, @c EINA_FALSE otherwise. + * @ingroup Ecore_X_DPMS_Group + */ +EAPI Eina_Bool +ecore_x_dpms_enabled_get(void) +{ + Eina_Bool ret = EINA_FALSE; +#ifdef ECORE_XCB_DPMS + xcb_dpms_info_cookie_t cookie; + xcb_dpms_info_reply_t *reply; +#endif + + LOGFN(__FILE__, __LINE__, __FUNCTION__); + CHECK_XCB_CONN; + + if (!_dpms_avail) return EINA_FALSE; + +#ifdef ECORE_XCB_DPMS + cookie = xcb_dpms_info_unchecked(_ecore_xcb_conn); + reply = xcb_dpms_info_reply(_ecore_xcb_conn, cookie, NULL); + if (!reply) return EINA_FALSE; + if (reply->state) ret = EINA_TRUE; + free(reply); +#endif + + return ret; +} + +/** + * Sets the DPMS state of the display. + * @param enabled @c 0 to disable DPMS characteristics of the server, enable it otherwise. + * @ingroup Ecore_X_DPMS_Group + */ +EAPI void +ecore_x_dpms_enabled_set(int enabled) +{ + LOGFN(__FILE__, __LINE__, __FUNCTION__); + CHECK_XCB_CONN; + + if (!_dpms_avail) return; + +#ifdef ECORE_XCB_DPMS + if (enabled) + xcb_dpms_enable(_ecore_xcb_conn); + else + xcb_dpms_disable(_ecore_xcb_conn); +#endif +} + +/** + * Gets the timeouts.
