MQDMHO - Delete message handle options

The MQDMHO structure allows applications to specify options that control how message handles are deleted. The structure is an input parameter on the MQDLTMH call.

Character set and encoding

Data in MQDMHO must be in the character set of the application and encoding of the application ( MQENC_NATIVE ).

Fields

Note: In the following table, the fields are grouped by usage rather than alphabetically. The child topics follow the same sequence.
Table 1. Fields in MQDMHO
Field name and description Name of constant Initial value (if any) of constant
StrucId (structure identifier) MQDMHO_STRUC_ID 'DMHO'
Version (structure version number) MQDMHO_VERSION_1 1
Options (options) MQDMHO_NONE 0
Notes:
  1. In the C programming language, the macro variable MQDMHO_DEFAULT contains the values that are listed in the table. It can be used in the following way to provide initial values for the fields in the structure: 
    
MQDMHO MyDMHO = {MQDMHO_DEFAULT};
