.SH DESCRIPTION
.sp
\fI\%memcached_touch()\fP is used to update the expiration time on an existing key.
\fI\%memcached_touch_by_key()\fP works the same, but it takes a master key
to find the given value.
.SH RETURN
.sp
A value of type \fBmemcached_return_t\fP is returned
On success that value will be \fBMEMCACHED_SUCCESS\fP\&.
Use \fBmemcached_strerror()\fP to translate this value to a printable
string.
