    NAME

    strnlen - determine the length of a fixed-size string
     
    

    SYNOPSIS

    #define _GNU_SOURCE
    
    #include <string.h>
    
    size_t strnlen(const char *s, size_t maxlen);
    
     

    DESCRIPTION

    The strnlen() function returns the number of characters in the string pointed to by s, not including the terminating aq\0aq character, but at most maxlen. In doing this, strnlen() looks only at the first maxlen characters at s and never beyond s+maxlen.  

    RETURN VALUE

    The strnlen() function returns strlen(s), if that is less than maxlen, or maxlen if there is no aq\0aq character among the first maxlen characters pointed to by s.  

    CONFORMING TO

    This function is a GNU extension.  

    SEE ALSO
