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; [components][drivers] Check macro "RT_USING_DFS" when using DFS relative method/functions. 2017-10-16T07:12:35Z ArdaFu pengfei.fu@gmail.com 2017-10-16T07:12:35Z urn:sha1:fc7abc658013d326d47145f85402cead0728b1a0 [DeviceDrivers] change cmd type. 2017-10-15T14:56:46Z bernard bernard.xiong@rt-thread.com 2017-10-15T14:56:46Z urn:sha1:d7087fdd3b998192afb03b34fd8034071d06bde7 1. Change 'rt_uint8_t' type of cmd to 'int'; 2. Add waitqueue; 3. Split device ipc header files; device/pipe: add a control cmd to get the space left in pipe 2013-10-22T17:43:18Z Grissiom chaos.proton@gmail.com 2013-10-22T17:43:18Z urn:sha1:0feefc03b6008301a19a430427390cc9c44decf8 dev/pipe: make pipe a type of device 2013-08-20T02:16:55Z Grissiom chaos.proton@gmail.com 2013-08-20T02:16:55Z urn:sha1:7e68096a88aaa9279507df54da191893be99f7df Pipe have many differences with char device. The main difference is altough pipe have both read and write, it is unidirectional in nature. dev/pipe: cleanup 2013-08-19T08:25:17Z Grissiom chaos.proton@gmail.com 2013-08-19T08:25:17Z urn:sha1:0340300f89a924b30fd8042b76686a236720d3d7 dev/pipe: call rx_indicate the time we resume reader 2013-08-19T07:57:59Z Grissiom chaos.proton@gmail.com 2013-08-19T07:57:59Z urn:sha1:e8cca2315a790d61c743a71e1a682e6ace7866fd Some reader(FinSh again) would like to block on a semaphore which is released in rx_indicate. So we should invoke rx_indicate in _rt_pipe_resume_reader. device/pipe: add nonblocking read/write and force write mode 2013-08-19T07:35:56Z Grissiom chaos.proton@gmail.com 2013-08-19T07:35:56Z urn:sha1:d683d32bd5502c15be600145966400a41710a7f4 The previous implementation will always blocks the reader/writer. However, at least FinSh would expect the device to be nonblocking --- read should return 0 when there is no data in it. device/pipe: add rt_pipe_{init,detach} 2013-08-19T04:28:59Z Grissiom chaos.proton@gmail.com 2013-08-19T04:24:15Z urn:sha1:38ce3879d8a98827338696e0b326ba6f6b1749f7 This provide the possibility that allocate the buffer of the ringbuffer on a specific region, instead of always mallocing it. It also bring us the benefit of using pipe device on the systems without heap.
