FTM_DATA_REQ_

This procedure allows you to transfer, or write, a block of data to a previously opened

file. The FTM_WRITE_REQ_ procedure must have been called to start the write

transfer before this procedure is called.

status return value

INT

indicates the outcome of the call. For a list of possible ZAPS-VAL-STATUS-xxx

values, see Table B-1 on page B-2.

cepi input

INT:value

is the connection endpoint identifier (CEPI) used to identify the specific

association. Use the CEPI value returned from the FTM_INITIALIZE_REQ_

procedure for this association. For additional information on using the cepi

parameter, see the OSI/FTAM Programming Guide.

cepi is a required parameter.

data-value input

STRING .EXT:ref:*

contains the data to be sent to the remote responder. This parameter consists of a

data header followed by a series of one or more data elements. The maximum

allowable size of the data-value parameter of an FTM_DATA_REQ_ call is

24 KB. For details on calculating the size of data-value, see the OSI/FTAM

Programming Guide.

data-value is a required parameter.

tag input

INT(32):value

is for use in nowait mode only. Specify a unique value to identify this instance of

the procedure call. When the operation is complete, the MFM_AWAITIOX_

procedure returns the tag value, allowing your application to match the completion

with the correct instance of the procedure call. For details on the use of the tag

parameter, see the OSI/FTAM Programming Guide.

tag is an optional parameter.

status := FTM_DATA_REQ_ ( cepi ! I

, data-value ! I

, [ tag ] ) ; ! I
