MQXWD - Exit wait descriptor

The MQXWD structure is an input/output parameter on the  MQXWAIT  call.

This structure is supported only on z/OS.

Fields

StrucId (MQCHAR4)

Structure identifier.

The value must be:

MQXWD_STRUC_ID

Identifier for exit wait descriptor structure.

For the C programming language, the constant MQXWD_STRUC_ID_ARRAY is also defined; this has the same value as MQXWD_STRUC_ID, but is an array of characters instead of a string.

The initial value of this field is MQXWD_STRUC_ID.

Version (MQLONG)

Structure version number.

The value must be:

MQXWD_VERSION_1

Version number for exit wait descriptor structure.

The initial value of this field is MQXWD_VERSION_1.

Reserved1 (MQLONG)

Reserved.

This is a reserved field; its value must be zero.

This is an input field.

Reserved2 (MQLONG)

Reserved.

This is a reserved field; its value must be zero.

This is an input field.

Reserved3 (MQLONG)

Reserved.

This is a reserved field; its value must be zero.

This is an input field.

ECB (MQLONG)

Event control block to wait on.

This is the event control block (ECB) to wait on. It should be set to zero before the  MQXWAIT  call is issued; on successful completion it will contain the post code.

This is an input/output field.
