Name
strnlen — determine the length of a fixed-size
string
Synopsis
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 '\0' 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 '\0'
character among the first maxlen characters pointed to by
s.
CONFORMING TO
This function is a GNU extension.
