<pre>
原型：extern void *memchr(void *buf, char ch, unsigned count);
用法：#include <string.h>
功能：從buf所指內存區域的前count個字節查找字符ch。
說明：當第一次遇到字符ch時停止查找。如果成功，返回指向字符ch的指針；否則返回NULL。
舉例：
// memchr.c
#include <syslib.h>
#include <string.h>
main()
{
char *s="Hello, Programmers!";
char *p;
clrscr();
p=memchr(s,'P',strlen(s));
if(p)
printf("%s",p);
else
printf("Not Found!");
getchar();
return 0;
}
