strnlen
Name
strnlen -- determine the length of a fixed-size string
Synopsis
size_t
strnlen
(const char
*s, size_t
maxlen);
Description
strnlen returns the number of characters in
the string 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
strnlen 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.
