嵌入式文件系统 EFSL 0.3.5 / 嵌入式文件系统 EFSL 0.3.5

This section of the manual describes the minimalistic C library functions that were
created for EFSL. Since EFSL was designed for ultimate portability, no assumptions about the
workings or even the presence of a C library could be made. Fortunately only very few functions
had to be created that mimicked the operations of well known C library functions.

	This function compares the strings \code{bufa} and \code{bufb} for \code{n} bytes.
	It will return the number of bytes in that section that does not match. So if you
	want to compare two strings the return value should be 0, for the strings to match over
	the entire \code{n} area.
