NAME
       tt_spec_prop  -  retrieve the ith value of the property associated with
       an object spec

SYNOPSIS
       #include <Tt/tt_c.h>
       char *tt_spec_prop(const char *objid,
                          const char *propname,
                          int i);

DESCRIPTION
       The tt_spec_prop() function retrieves the ith  value  of  the  property
       associated with this object spec.

       The  objid  argument  is  the identifier of the object involved in this
       operation.  The propname argument is the name of the  property  associ-
       ated  with  the  object  spec.   The i argument is the item of the list
       whose value is to be retrieved.  The list numbering begins with zero.

RETURN VALUE
       Upon successful completion, the  tt_spec_prop()  function  returns  the
       contents  of  the  property  value.   If  there  are  i values or less,
       tt_spec_prop() returns NULL.  The application can  use  tt_ptr_error(3)
       to  extract  one  of  the  following Tt_status values from the returned
       pointer:

          TT_OK   The operation completed successfully.

          TT_ERR_DBAVAIL
                  The ToolTalk service could not access the ToolTalk  database
                  needed for this operation.

          TT_ERR_DBEXIST
                  The ToolTalk service could not access the specified ToolTalk
                  database in the expected place.

          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_OBJID
                  The  objid passed to the ToolTalk service does not reference
                  an existing object spec.

          TT_ERR_PROPNAME
                  The specified property name is syntactically invalid.

APPLICATION USAGE
       The application should use tt_free(3) to free any data  stored  in  the
       address returned by the ToolTalk API.

       If  the  returned value has embedded nulls, its length cannot be deter-
       mined.
