strncpy

Item Value Header file string.h Declaration char *strncpy(char *str1, const char *str2, size_t count); Function copies up to count characters from *str2 to *str1. Return returns a pointer to str1.

1. str2 must be a pointer to a null-terminated string.
2. If *str2 has less than "count" characters, nulls will be appended to *str1 until count characters have been copied.
3. If *str2 is longer than count characters, the result *str1 will not be null terminated.
