CCDTUrlPtr (PMQCHAR)

CCDTUrlPtr is an optional pointer to a string which contains a URL, to identify the location of the client connection channel table to use for the connection.. This field is an input field, with an initial value of a null pointer in programming languages that support pointers, and an all-null byte string otherwise.

Use CCDTUrlPtr only when the application issuing the MQCONNX call is running as an IBM® MQ MQI client.

Important: You can use only one of CCDTUrlPtr and CCDTUrlOffset. The call fails with reason code MQRC_CCDT_URL_ERROR if both fields are nonzero.

This is a programmatic alternative to setting the MQCHLLIB and MQCHLTAB environment variables.

If the application is not running as an client, CCDTUrlPtr is ignored.

This field is ignored if Version is less than MQCNO_VERSION_6.
