NAME

       tt_message_arg_bval_set -- set the byte-array value and type of a message argument

SYNOPSIS

       #include <Tt/tt_c.h>
       Tt_status tt_message_arg_bval_set(
       Tt_message m,
       int n,
       const unsigned char *value,
       int len);

DESCRIPTION

       The tt_message_arg_bval_set function sets the byte-array value and the type of the nth message argument.

       This function also changes the value of an existing nth message argument to a byte string.

       The  m argument is the opaque handle for the message involved in this operation.  The n argument is the number of the argument to set.  The
       first argument is numbered zero.  The value argument is the byte string with the contents for the message argument.  The  len  argument	is
       the length of the value in bytes.

RETURN VALUE

       Upon successful completion, the tt_message_arg_bval_set function returns the status of the operation as one of the following Tt_status val-
       ues:

       TT_OK	 The operation completed successfully.

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

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

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

APPLICATION USAGE

       The sending process can use tt_message_arg_bval_set(3) to fill in opaque data.
