NAME 🖥️ strnlen 🖥️

determine the length of a fixed-size string

LIBRARY

Standard C library (libc, -lc)

SYNOPSIS

#include <string.h>
size_t strnlen(const char s[.maxlen], size_t maxlen);

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

strnlen():

    Since glibc 2.10:
        _POSIX_C_SOURCE >= 200809L
    Before glibc 2.10:
        _GNU_SOURCE

DESCRIPTION

The strnlen() function returns the number of bytes in the string pointed to by s, excluding the terminating null byte (‘�’), but at most maxlen. In doing this, strnlen() looks only at the first maxlen characters in the string pointed to by s and never beyond s[maxlen-1].

RETURN VALUE

The strnlen() function returns strlen(s), if that is less than maxlen, or maxlen if there is no null terminating (‘�’) among the first maxlen characters pointed to by s.
