Let's see if this helps:
From setsockopt()'s manpage:
[...]
Most socket-level options utilize an int parameter for option_value. For
setsockopt(), the
parameter should be non-zero to enable a boolean option, or zero if the
option is to be dis-
abled. SO_LINGER uses a struct linger parameter, defined in
<sys/socket.h>, which specifies
the desired state of the option and the linger interval (see below).
SO_SNDTIMEO and
SO_RCVTIMEO use a struct timeval parameter, defined in <sys/time.h>.
[...]
SO_SNDTIMEO is an option to set a timeout value for output operations. It
accepts a struct
timeval parameter with the number of seconds and microseconds used to
limit waits for output
operations to complete. If a send operation has blocked for this much
time, it returns with a
partial count or with the error EWOULDBLOCK if no data were sent. In the
current implementa-
tion, this timer is restarted each time additional data are delivered to
the protocol, imply-
ing that the limit applies to output portions ranging in size from the
low-water mark to the
high-water mark for output.
[...]
And I can see this in the header files:
/usr/include/sys/_structs.h:
#define _STRUCT_TIMEVAL struct timeval
_STRUCT_TIMEVAL
{
__darwin_time_t tv_sec; /* seconds */
__darwin_suseconds_t tv_usec; /* and microseconds */
};
/usr/include/sys/types.h:
typedef __darwin_time_t time_t;
typedef __darwin_suseconds_t suseconds_t;
/usr/include/sys/_types.h:
typedef __int32_t __darwin_suseconds_t; /* [???] microseconds */
Hope it helps.
