Linux system call list (GO)

The following is a list of Linux system calls that contain most of the common system calls and functions derived from system calls. This is probably the only list of Linux system calls you can see on the Internet, even if it's a simple alphabetical list, it's very rare to be able to do so completely.

By convention, this list is modelled on the Man Pages section 2nd, the System invocation section. According to the author's understanding, the general classification, but also made some minor changes, deleted a few for the kernel, not allow users to call the system calls, the individual I slightly feel inappropriate place made some minor changes, and all listed system calls attached a brief comment.

Some of these functions work exactly the same way, except for different parameters. (maybe a lot of familiar C + + friends can immediately associate with the function overload, but do not forget that the Linux core is written in C, so it can only be used for different function names). Some of the functions are obsolete, replaced by new better functions (GCC warns when linking these functions), but because of the reasons for compatibility, these functions will be marked with "*" on the front.
