1.全局变量tperrno
当一个ATMI调用发生错误时，全局变量tperrno被设置，它指示发生错误的原因。可选值如下：
代码 解释 TPEABORT Transaction can not commit TPEBADDESC Bad descriptor for tpgetrply(3c) TPEBLOCK Blocking condition found and no-block specified TPEINVAL Invalid arguments given TPELIMIT Too many handles outstanding TPENOENT No entry found or no room on the Bulletin Board TPEOS Operating system error TPEPERM Bad permissions or failed authentication TPEPROTO Protocol error TPESVCERR Server error while handling request TPESVCFAIL Application level service failure TPESYSTEM Internal BEA TUXEDO error (userlog(3c)) message written) TPETIME Time-out occurred and TPNOTIME was not specified TPETRAN Caller in transaction mode and transaction aborted TPGOTSIG Signal received and TPSIGRSTRT not specified TPERMERR Resource Manager failure TPEITYPE Type and/or subtype do not match services TPEOTYPE Type and/or subtype do not match buffers or unknown TPERELEASE Caller has made a 3.0 library call TPEHAZARD Hazard exists that transaction heuristically completed TPEHEURISTIC Transaction heuristically completed TPEEVENT Event occurred TPEMATCH Service name cannot be advertised due to matching conflict

2.错误函数tpstrerror

根据错误号tperrno生成一个错误信息串，把串的起始地址返回。
当错误是TPESYSTEM或TPEOS时，一个消息写到userlog文件。
