Noteworthy C-Lib Changes Refactoring (thanks to TANGO) Use gIsCyclePollingMode instead of POLLING , SELECTING . e.g. becomes linkTbl mutex protection inside checkConnections().
Noteworthy C-Lib Changes linkTbl mutex protection Notice anything suspicious ?
Noteworthy C-Lib Changes avoid a potential deadlock when debugging is ON and there are send socket errors also in this regard: treat 'printf' as a 'send' (as it is on VxWorks). inside dbglog() : dbgprintf() :
Noteworthy C-Lib Changes VxWorks task trace .
Noteworthy C-Lib Changes introduce Set/GetSuspendCallbacks() e.g. use around calls to ExecLink() added a 'flush address' and 'flush cache' to the console commands To force server address reacquisition now ! fixed timereq = 0 in _attachLink so as to avoid long wait in establishing TCP connection From prepSubRequest()
Noteworthy C-Lib Changes long wait in establishing TCP connection Anywhere from 0 to 1000 msec ! Was not caught by unit server/unit client Now it is!
Noteworthy C-Lib Changes respect the bound and mca links in getLinkIdFromCallbackId() Necessary addition !
Noteworthy C-Lib Changes Set/GetPutCommandsInCmdlog() to accompany the new commands.log commands.log in addition to fec.log add routine sckadrcmp() to replace a memcmp() on a comparison of SCKADR objects used in access lock comparison.
