NAME
     tt_session_bprop_set - replace current values  stored  under
     the named property of a session

SYNOPSIS
     #include <Tt/tt_c.h>
     Tt_status tt_session_bprop_set(const char *sessid,
                                    const char *propname,
                                    const unsigned char *value,
                                    int length);

DESCRIPTION
     The tt_session_bprop_set()  function  replaces  any  current
     values stored under the named property of the specified ses-
     sion with the given byte-string value.

     The sessid argument is the name of the session joined.   The
     application   can   use   the  sessid  value  returned  when
     tt_default_session() is called.  The  propname  argument  is
     the name of the property whose value is to be replaced.  The
     value argument is the value to which the session property is
     set.   If  value  is NULL, the property is removed entirely.
     The length argument is the size of the value in bytes.

RETURN VALUE
     Upon successful completion, the tt_session_bprop_set() func-
     tion  returns the status of the operation as one of the fol-
     lowing 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_PROPLEN
                The specified property value is too  long.   (The
                maximum  size  is implementation specific, but is
                at least 2048.)

        TT_ERR_PROPNAME
                The  specified  property  name  is  syntactically
                invalid.

        TT_ERR_SESSION
                The specified ToolTalk session is out of date  or
                invalid.
