GNU与GPL UNIX诞生后，很多教育机构、大型企业都投入研究，研究成果不同，造成了一些经济利益和版权问题。早期计算机程序的源代码(Source Code)都是公开的，到20世纪70年代，源代码开始对用户封闭。UNIX爱好者Richard M.Stallman提出开放源码(Open Source)的概念，提倡大家共享自己的程序，让众人参与校验，在不同平台测试...
POSIX.1 takes a "write once, adopt everywhere" approach to the specifications by providing a set of fundamental services needed to efficiently build applications. The standard emphasizes the facilities and characteristics that are important to application development, rather than focusing on the technique...
source 可以是任意一个名字(通常将其指定为字符串 none),其唯一的意义是它将出现在/proc/mounts 中并且 mount 和 df 命令会显示出这个名字。 target 是消息队列文件系统的挂载点。下面的 shell 会话显示了如何挂载消息队列文件系统和显示其内容。首先为文件系统创建一个挂载点并挂载它。接着显示新挂载在/proc/...
POSIX. 1-2008 defines a standard operating system interface and environment, including a command interpreter (or "shell"), and common utility programs to support applications portability at the source code level. POSIX. 1-2008 is intended to be used by both application developers and system ...
IEC 101 源代码库支持 Windows、嵌入式 Linux(ARM、Coldfire、Power PC)、Ubuntu Linux(X86、X86-64)、Fedora、CentOS、Red Hat、PowerPC、QNX 等。 内存占用低,易于在任何硬件平台上启动,可以在有或没有操作系统的情况下运行,作为源代码交付,高配置允许仅使用所需

POSIX.1 defines a C language source code-level application programming interface (API) to an operating system environment POSIX Systems POSIX was designed as a standard environment to enable the portability of software applications. The portability of a software application is achieved through the speci...
_XOPEN_SOURCE >= 600 || _POSIX_C_SOURCE >= 200112L mq_send() 把msg_ptr指向的消息加入由mqdes引用的消息队列里。参数msg_len指定消息msg_ptr的长度:这个长度必须小于或等于队列mq_msgsize属性的值。零长度的消息是允许。 msg_prio是一个用于指定消息优先级的非负整数。消息在队列里依据优先级排序,相同...
si_code 域将被设置为 SI_MESGQ。进一步说, si_pid 将被设置为发送消息的进程的进程 ID,同时 si_uid 将被设置为发送进程的真实用户 ID。 SIGEV_THREAD 当消息到达时,启动一个新线程来调用 sigev_notify_function。参见 sigevent(7) 来了解其中细节。
