The first parameter of this function specifies the process to be restricted, and the second parameter is a "bit shielded" data. Each bit in it represents a CPU code (starting from 0 ), for example, 0x00000001 indicates that CPU 0 is selected, that is, "threads in the process" can only run on CPU 0; 0x00000005 indicates that both CPU 0 and CPU 2 are selected.

short from 0x00000002-0x00000003 The second takes a short from 0x00000004-0x00000005 and then combines the desired data, and if the variable is on the 0x00000003 address, it accesses three memory, the first char, the second is short, and the third is char, Then combine to get the integer data. If the variable is in the natural alignment position, the data can be fetched once. Some systems have strict alignment requirements, such as SPARC systems, whe
