DESCRIPTION

The tt_spec_bprop function retrieves the ith value of the specified property.

The objid argument is the identifier of the object involved in this operation. The propname argument is the name of the property whose value is to be retrieved. The name must be less than 64 characters. The i argument is the item of the list for which a value is to be obtained. The list numbering begins with zero. The value argument is the address of a character pointer to which the ToolTalk service is to point a string that contains the contents of the spec's property. If there are i values or fewer, the pointer is set to zero. The length argument is the address of an integer to which the ToolTalk service is to set the length of the value in bytes.
