c语言_头文件_stdlib
简介
stdlib 头文件即standard library标准库头文件
stdlib 头文件里包含了C、C++语言的最常用的系统函数
该文件包含了C语言标准库函数的定义
stdlib.h里面定义了五种类型、一些宏和通用工具函数。 类型例如size_t、wchar_t、div_t、ldiv_t和lldiv_t； 宏例如EXIT_FAILURE、EXIT_SUCCESS、RAND_MAX和MB_CUR_MAX等等； 常用的函数如malloc()、calloc()、realloc()、free()、system()、atoi()、atol()、rand()、srand()、exit()等等。 具体的内容你自己可以打开编译器的include目录里面的stdlib.h头文件看看。
