Depending on the version of Open Transport, the size of the OTCfgTCPLocks
structure is 25 bytes (pre-Open Transport 2.0) or 27 bytes (Open Transport 2.0
and later). The following preference size constants are defined for this structure:
enum {
kOTCfgTCPLocksPrefPre2_0Size = 25,
kOTCfgTCPLocksPref2_0Size = 27,
kOTCfgTCPLocksPrefCurrentSize = kOTCfgTCPLocksPref2_0Size,
};
When reading or writing this preference, be sure to use the appropriate
preference type for the version of Open Transport that is being used.
The preference type for OTCfgTCPLocks is kOTCfgTCPLocksPref, which is defined
as 'stng'.
