6.58 Other Built-in Functions Provided by GCC(点击打开链接)这个页面最后面三个函数就是我们需要的: — Built-in Function: uint16_t __builtin_bswap16 (uint16_t x) Returns x with the order of the bytes reversed; for example, 0xaabb becomes 0xbbaa. Byte here always means exactly 8 bits./...
Build-in Function,启动python解释器,输入dir(__builtins__), 可以看到很多python解释器启动后默认加载的属性和函数,这些函数称之为内建函数, 这些函数因为在编程时使用较多,cpython解释器用c语言实现了这些函数,启动解释器 时默认加载。 这些函数数量众多,不宜记忆,开发时不是都用到的,待用到时再help(function), ...

This example describes the use of mapping rules during a migrate of a directory and files on a UNIX file system.
Matrices may be transposed using the built-in transpose() function. If you transpose a non-square matrix, its dimensions are simply swapped. transpose函数可以用来把一个矩阵进行转置,如果你转置的是一个非方阵,那么行数和列数与原始的矩阵是互换了的。 To find the inverse of a matrix, GLSL provides...
