错误消息处理
索引：
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
char *tpstrerror(int tperrno);
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。
