Constants and Data Types

The Linger Structure

The linger structure specifies the value of the XTI_LINGER option, described in "XTI-Level Options" (page 5-25).

The linger structure is defined by the t_linger data type.

struct t_linger 
   {
   long l_onoff;  /* option on/off */
   long l_linger; /* linger time */
   };

Field Description

l_onoff

A constant specifying whether the option is turned on (T_ON) or off (T_OFF).

l_linger

An integer specifying the linger time, the amount of time in seconds that Open Transport should wait to allow data in an endpoint's internal buffer to be sent before the OTCloseProvider function closes the endpoint.

To request the default value for this option, set the l_linger field to T_UNSPEC.
