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

     strlen, strnlen -- find length of string

     Standard C Library (libc, -lc)

     #include <string.h>

     strlen(const char *s);

     strnlen(const char *s, size_t maxlen);

     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.

     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.

     string(3), wcslen(3), wcswidth(3)

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