opcode

AP_QUERY_MDS_APPLICATION

overlay_size

For compatability with future releases of SNAplus2,

your application must use this ﬁeld to determine the

exact length of the overlay structure returned, and

should not rely on the use of the sizeof() function.

buf_ptr

A pointer to a data buffer that SNAplus2 will use to

return the requested information.

buf_size

Size of the supplied data buffer.

num_entries

Maximum number of applications for which data

should be returned. To request data for a speciﬁc

application rather than a range, specify the value 1.To

return as many entries as possible, specify zero; in this

case, SNAplus2 will return the maximum number of

entries that can be accommodated in the supplied data

buffer.

list_options

The position in the list of applications from which

SNAplus2 should begin to return data. Possible values

are:

AP_FIRST_IN_LIST

Start at the ﬁrst entry in the list.

AP_LIST_INCLUSIVE

Start at the entry speciﬁed by the application

parameter.

AP_LIST_FROM_NEXT

Start at the entry immediately following the entry

speciﬁed by the application parameter.
