<h1>字符串函数 - bcmp</h1>
|
|
|
|
|
|
<p>原型:extern int bcmp(const void *s1, const void *s2, int n);</p>
|
|
|
|
<p>用法:#include <string.h></p>
|
|
|
|
<p>功能:比较字符串s1和s2的前n个字节是否相等</p>
|
|
|
|
<p>说明:如果s1=s2或n=0则返回零,否则返回非零值。bcmp不检查NULL。</p>
|
|
|
|
举例:<pre><code class="language-c">
|
|
|
|
// bcmp.c
|
|
|
|
#include <syslib.h>
|
|
#include <string.h>
|
|
|
|
main()
|
|
{
|
|
char *s1="Golden Global View";
|
|
char *s2="Golden global view";;
|
|
|
|
clrscr(); // clear screen
|
|
if(!bcmp(s1,s2,7))
|
|
printf("s1 equal to s2 in first 7 bytes");
|
|
else
|
|
printf("s1 not equal to s2 in first 7 bytes");
|
|
|
|
getchar();
|
|
clrscr();
|
|
if(!bcmp(s1,s2,12))
|
|
printf("s1 equal to s2 in first 12 bytes");
|
|
else
|
|
printf("s1 not equal to s2 in first 12 bytes");
|
|
|
|
getchar();
|
|
return 0;
|
|
}
