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 asso‐
ciated 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 con‐
tents 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_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.
