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 inter-
preted 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:
TT_IN The argument is written by the sender and read by the han-
dler and any observers.
TT_OUT
The argument is written by the handler and read by the
sender and any reply observers.
TT_INOUT
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 serial-
ize 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:
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 cor-
rect type for this operation.
TT_ERR_XDR
The XDR procedure failed on the given data, or evaluated to
a zero-length expression.
