 NAME    [Toc]    [Back]
      tt_pattern_barg_add - add an argument with a value that contains
      embedded nulls to a pattern

 SYNOPSIS    [Toc]    [Back]
      #include <Tt/tt_c.h>
      Tt_status tt_pattern_barg_add(
      Tt_pattern m,
      Tt_mode n,
      const char *vtype,
      const unsigned char *value,
      int len);

 DESCRIPTION    [Toc]    [Back]
      The tt_pattern_barg_add function adds an argument with a value that
      contains embedded nulls to a pattern.

      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 message argument.  The following modes are defined:

      TT_IN     The argument is written by the sender and read by the
                handler 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.
      Type ALL matches any argument value type.

      The ToolTalk service treats the value as an opaque byte string.  To
      pass structured data, the application and the receiving application
      must encode and decode these unique values.  The most common method to
      use is XDR.

      The value argument is the value to be added.  NULL matches any value.

      The len argument is the length of the value in bytes.

 RETURN VALUE    [Toc]    [Back]
      Upon successful completion, the tt_pattern_barg_add 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.
