tt_pattern_xarg_add(3)

NAME
tt_pattern_xarg_add - add a new argument with an interpreted XDR value to a pattern object

SYNOPSIS
#include <Tt/tt_c.h>

Tt_status tt_pattern_xarg_add(Tt_pattern m,
	Tt_mode n,
	const char *vtype,
	xdrproc_t xdr_proc,
	void *value);

DESCRIPTION
The tt_pattern_xarg_add() function adds a new argument with an interpreted XDR value to a pattern object.

The m argument is the opaque handle for the pattern involved in this operation. The n argument specifies who (sender, handler, observers) writes and reads a pattern argument. The following modes are defined:

    The argument is written by the sender and read by the handler and any observers.
    The argument is written by the handler and read by the sender and any reply observers.
    The argument is written by the sender and the handler and read by all.

The vtype argument describes the type of argument data being added. The xdr_proc argument points to the XDR procedure to be used to serialize the data pointed to by value. The value argument is the data to be serialized.

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

    The operation completed successfully.
    The specified Tt_mode is invalid.
    The ttsession(1) process is not running and the ToolTalk service cannot restart it.
    The pointer passed does not point to an object of the correct type for this operation.
    The XDR procedure failed on the given data, or evaluated to a zero-length expression.
