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.
