     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
     values:

        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.
