slightly cleaner strlen, also seems to compile to better code

[musl] / src / string / strncmp.c

#include <string.h>

int strncmp(const char *_l, const char *_r, size_t n)
{
        const unsigned char *l=(void *)_l, *r=(void *)_r;
        if (!n--) return 0;
        for (; *l && *r && n && *l == *r ; l++, r++, n--);
        return *l - *r;
}
