APPC Conversation Verbs
MC_SEND_DATA and SEND_DATA
Number of bytes of data to be put in the local LU’s send buffer. The range for this value is 0–65,535.
dptr
Address of the buffer containing the data to be put in the local LU’s send buffer.
WINDOWS
The data buffer can reside in a static data area or in a globally allocated area. The data buffer must fit entirely
within this area.
type
Specifies whether to perform the function of another APPC verb in addition to [MC_]SEND_DATA. Possible
values are:
AP_NONE
Send data only—do not perform any additional function.
AP_SEND_DATA_CONFIRM
This option is valid only in a half-duplex conversation. Do not use it if the opext parameter includes
the option AP_FULL_DUPLEX_CONVERSATION.
Perform the function of the [MC_]CONFIRM verb. This is equivalent to issuing [MC_]SEND_DATA
followed by [MC_]CONFIRM. For the basic-conversation SEND_DATA verb, the data sent on this
verb must be a complete logical record or the end of a logical record; this value cannot be used if an
incomplete logical record is being sent.
AP_SEND_DATA_FLUSH
Perform the function of the [MC_]FLUSH verb. This is equivalent to issuing [MC_]SEND_DATA
followed by [MC_]FLUSH. For the basic-conversation SEND_DATA verb, the data sent on this verb
must be a complete logical record or the end of a logical record; this value cannot be used if an
incomplete logical record is being sent.
AP_SEND_DATA_P_TO_R_FLUSH
This option is valid only in a half-duplex conversation. Do not use it if the opext parameter includes
the option AP_FULL_DUPLEX_CONVERSATION.
Perform the function of the [MC_]PREPARE_TO_RECEIVE verb with ptr_type set to AP_FLUSH.
This is equivalent to issuing [MC_]SEND_DATA followed by [MC_]PREPARE_TO_RECEIVE. For
the basic-conversation SEND_DATA verb, the data sent on this verb must be a complete logical record
or the end of a logical record; this value cannot be used if an incomplete logical record is being sent.
AP_SEND_DATA_P_TO_R_CONFIRM
This option is valid only in a half-duplex conversation. Do not use it if the opext parameter includes
the option AP_FULL_DUPLEX_CONVERSATION.
Perform the function of the [MC_]PREPARE_TO_RECEIVE verb with ptr_type set to
AP_CONFIRM_TYPE. This is equivalent to issuing [MC_]SEND_DATA followed by
[MC_]PREPARE_TO_RECEIVE. For the basic-conversation SEND_DATA verb, the data sent on this
verb must be a complete logical record or the end of a logical record; this value cannot be used if an
incomplete logical record is being sent.
AP_SEND_DATA_P_TO_R_SYNC_LEVEL
This option is valid only in a half-duplex conversation. Do not use it if the opext parameter includes
the option AP_FULL_DUPLEX_CONVERSATION.
Perform the function of the [MC_]PREPARE_TO_RECEIVE verb with ptr_type set to
AP_SYNC_LEVEL. This is equivalent to issuing [MC_]SEND_DATA followed by
