One of these magics was, on nearly every platform, to provide its own declarations for every library function and system call it planned to use, rather than including the standard headers.
其中最奇妙的事情之一是，在几乎每个平台上都为计划要处理的每个库函数和系统调用都提供自己的声明，而不是包括标准的头文件。
Since the MASS vector functions are much faster (by a factor of up to about 30) than a repeated call to a standard library function, the resulting performance improvement can be substantial.
因为MASS向量函数要比对一个标准库函数的重复访问快很多(倍数接近30倍)，所以最后得到的性能改善效果将会是惊人的。
This call, should it succeed, yields the address of the first copy of the function found in a library after the one in which the call occurs.
在一个函数中进行调用之后，如果成功的话，这个调用处理库中找到的该函数的第一个副本。
