Add macro check in rtdebug.h; 2. Use RT_USING_POSIX for poll/select, stdin etc. 3. Split dfs_posix.h to dfs_posix.h, dfs_poll.h and dfs_select.h; [Kernel] Add signal implementation. 2017-10-15T14:31:53Z bernard bernard.xiong@rt-thread.com 2017-10-15T14:31:53Z urn:sha1:b27c7e482648535760e012cd6f1afef1d800e2d2 1. Add signal implementation; 2. Change the 'rt_uint8_t' of cmd to 'int'; fix the open_flag initialization issue. 2016-04-02T06:42:38Z Bernard Xiong bernard.xiong@gmail.com 2016-04-02T06:42:38Z urn:sha1:daf488ca7736b4fb940277121f852c3037e26934 Update device.c 2014-09-19T06:29:03Z Bernard Xiong bernard.xiong@gmail.com 2014-09-19T06:29:03Z urn:sha1:bd6b39cace67fcefccb105e0e6f7609973bbb7ce [Kernel] Better documentation for doxygen. 2014-07-20T22:29:15Z bernard bernard.xiong@gmail.com 2014-07-20T22:29:15Z urn:sha1:33fed1b167e1b2a653d9e58853537e40628f4e2e [Kernel] Remove rt_device_init_all implemetation. 2014-07-10T05:34:52Z bernard bernard.xiong@gmail.com 2014-07-10T05:34:52Z urn:sha1:1e7b0894949be4fe86c31ddf3c1bd754908459aa device: only increase the ref_count when device is truly opened 2014-06-18T03:16:21Z Grissiom chaos.proton@gmail.com 2014-06-18T03:16:21Z urn:sha1:dc366ecf7a2946c8f071735f5f2065d51000240a device: add ref_count support 2013-07-09T07:44:55Z Grissiom chaos.proton@gmail.com 2013-07-09T03:54:50Z urn:sha1:7bcce9e87fa987d4bb88d48d3f7d0aca58963e74 This is a simple work around to the current device stack design. A ref_count could let different modules to open/close the same device independently without interfere others in some degree. But there is still some data shared between the modules, like flag, open_flag and user_data. Moreover, it won't yield an error if A open a device, and B read from it before open it in B. Maybe alloc a new handle in rt_device_open will be the ultimate solution. But that is much bigger change and we may leave it to future development.
