strlen, strnlen —
#include <string.h>
size_t
  
  strlen(const
    char *s);
size_t
  
  strnlen(const
    char *s, size_t
    maxlen);
strlen() function computes the length of the string
  s.
The strnlen() function attempts to compute
    the length of s, but never scans beyond the first
    maxlen bytes of s.
strlen() function returns the number of characters
  that precede the terminating NUL character.
The strnlen() function returns either the
    same result as strlen() or
    maxlen, whichever is smaller.
strlen() function conforms to
  ISO/IEC 9899:1990 (“ISO C90”).
  The strnlen() function conforms to
  IEEE Std 1003.1-2008 (“POSIX.1”).
