Any comments, suggestions, swears concerning adding a new function,
strndup(), to libc?
So that instead of permitting it to attempt to allocate a large chunk of
memory, it is possible to give it a max length.
char *
strndup(str, max_len)
const char *str;
size_t max_len;
{
size_t len;
char *copy;
len = strlen(str) + 1;
if (len > max_len)
len = max_len;
if ((copy = malloc(len)) == NULL)
return (NULL);
memcpy(copy, str, len);
return (copy);
}
