NetBSD 6.1.5 - man page for strlen (netbsd section 3)

STRLEN(3)			   BSD Library Functions Manual 			STRLEN(3)

NAME
     strlen, strnlen -- find length of string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     size_t
     strlen(const char *s);

     size_t
     strnlen(const char *s, size_t maxlen);

DESCRIPTION
     The 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.

RETURN VALUES
     The 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.

SEE ALSO
     string(3), wcslen(3), wcswidth(3)

STANDARDS
     The strlen() function conforms to ISO/IEC 9899:1990 (``ISO C90'').  The strnlen() function
     conforms to IEEE Std 1003.1-2008 (``POSIX.1'').
