MQWXP 的初始值和语言声明

MQWXP -集群工作负载出口参数结构的初始值以及 C 和 High Level Assembler 语言声明。

表 1. MQWXP 中字段的初始值
字段名称 常量的名称 常量值
StrucId MQWXP_STRUC_ID 'WXP¬'
Version MQWXP_VERSION_2 2
ExitId None 0
ExitReason MQXCC_OK 0
ExitResponse None 0
ExitResponse2 None 0
Flags None 0
ExitUserArea {MQXUA_NONE_ARRAY} 0
ExitData None
MsgDescPtr None NULL
MsgBufferPtr None NULL
MsgBufferLength None 0
MsgBufferPtr None 0
QName None
QMgrName None
DestinationCount None 0
DestinationChosen None 0
DestinationArrayPtr None NULL
QArrayPtr None NULL
CacheContext None NULL
CacheType MQCLCT_DYNAMIC 1
CLWLMRUChannels None 0
pEntryPoints None NULL
备注信息：
  1. 符号 ¬ 表示单个空白字符。
  2. 在 C 编程语言中，宏变量 MQWXP_DEFAULT 包含缺省值。 通过以下方式使用它来为结构中的字段提供初始值:
    MQWDR MyWXP = {MQWXP_DEFAULT};
