strncpy

Copies not more than n characters from the string pointed to by s2 to the array pointed to

by s1. If copying takes place between objects that overlap, the behavior is undefined.

If the string pointed to by s2 is shorter than n characters, null characters are appended to

the copy in the array pointed to by s1, until n characters in all have been written.

char *strncpy(char *s1, const char *s2, size_t n);

Returns

The value of s1.

Example

char *ptr;

char s1[40]="Production";

char s2[]="Languages";

ptr=strncpy(s1,s2,4);

strpbrk

Locates the first occurrence in the string pointed to by s1 of any character from the string

pointed to by s2.

Synopsis

#include <string.h>

char *strpbrk(const char *s1, const char *s2);

Returns

A pointer to the character, or a null pointer if no character from s2 occurs in s1.

char s1[]="COMPASS";

char s2[]="PASS";
