tt_message_arg_xval(3)
CDE
NAME
  tt_message_arg_xval - retrieve and deserialize the data from a message
  argument

SYNOPSIS
  #include <Tt/tt_c.h>
  Tt_status tt_message_arg_xval(Tt_message m,
				int n,
				xdrproc_t xdr_proc,
				void **value);

DESCRIPTION
  The tt_message_arg_xval function retrieves and deserializes the data from a
  message argument. This function uses an XDR routine that is supplied by the
  client.

  The m argument is the opaque handle for the message involved in this
  operation. The n argument is the number of the argument to be returned. The
  first argument is numbered zero. The xdr_proc argument points to the XDR
  procedure to be used to deserialize the data in the nth argument into newly
  allocated storage, the address of which will be stored in the pointer whose
  address is value.

  The value argument is the data to be deserialized.

RETURN VALUE
  Upon successful completion, the tt_message_arg_xval function returns the
  status of the operation as one of the following Tt_status values:

  TT_OK
      The operation completed successfully.

  TT_ERR_MODE
      The specified Tt_mode is invalid.

  TT_ERR_NOMP
      The ttsession(1) process is not running and the ToolTalk service cannot
      restart it.

  TT_ERR_POINTER
      The pointer passed does not point to an object of the correct type for
      this operation.

  TT_ERR_NUM
      The integer value passed was invalid (out of range).

  TT_ERR_XDR
      The XDR procedure failed on the given data, or evaluated to a zero-
      length structure.

APPLICATION USAGE
  The allocation calls are made by the XDR procedure; therefore, any storage
  allocated is not allocated from the ToolTalk allocation stack. The
  application should use the xdr_free(3) call to free this storage.
