strnlen — determine the length of a fixed-size string
#define _GNU_SOURCE #include <string.h>
size_t strnlen( |
const char * | s, |
| size_t | maxlen); |
The strnlen() function
returns the number of characters in the string pointed to by
s, not including the
terminating '\0' character, but at most maxlen. In doing this,
strnlen() looks only at the
first maxlen
characters at s and
never beyond s+maxlen.
The strnlen() function
returns strlen(s),
if that is less than maxlen, or maxlen if there is no '\0'
character among the first maxlen characters pointed to by
s.
