1、Tpinit//传递客户认证信息Tpalloc//申请缓冲区Tpcall//调用服务Tpfree//释放指向缓冲区的指针Tpsvrinit//服务启动前的一个初始化Tpsvrdone//关闭服务之前自动调用Tpreturn//响应后返回信息char*tpalloc(char*type,char*subtype,longsize)Type用于指定缓冲区类型,可取值STRINGFMLXML等Subtype用于指定缓冲区子类型,仅在分配VIEW缓冲区时,指定对应的C结构名,对于其它缓冲区来说,填NULLSize
2、是缓冲区大小,以字节为单位,如1024表示分配1KB缓冲区Tpalloc返还分配缓冲区的指针,返还NULL标识分配失败voidtpfree(char*ptr)Ptr是要释放的缓冲区的指针Tpfree没有返还值,也就是说不用判断它是否成功的释放了缓冲区inttpcall(char*svc,char*idata,longilen,char**odata,long*olen,longflags)Svc是要调用的服务名Idata是请求缓冲区指针,ilen是请求缓冲区长度Odata是指向响应缓冲区指针的指针,使用双
3、重指针的目的是便于动态调整响应缓冲区的大小Client:/*(c)2003BEASystems,Inc.AllRightsReserved.*//*Copyright(c)1997BEASystems,Inc.AllrightsreservedTHISISUNPUBLISHEDPROPRIETARYSOURCECODEOFBEASystems,Inc.Thecopyrightnoticeabovedoesnotevidenceanyactualorintendedpublicationofsuchsour
