Constants and Data Types

This section describes the basic configuration management constants, the Gestalt function selector and response bits, the configuration structure, the port structure, and the port reference structure.

These constants provide length and size values for modules, provider names, and slot IDs. These fields all end with a byte for the terminating zero. The constant kMaxProviderNameSize permits a length of 36 bytes: 31 bytes for the name, up to 4 bytes of extra characters (called minor numbers in Streams specifications, and currently not used), and a byte for the zero that terminates the string.

enum {
   kMaxModuleNameLength    = 31,
   kMaxModuleNameSize      = kMaxModuleNameLength + 1,
   kMaxProviderNameLength  = kMaxModuleNameLength + 4,
   kMaxProviderNameSize    = kMaxProviderNameLength + 1,
   kMaxSlotIDLength        = 7,
   kMaxSlotIDSize          = 8,
   kMaxResourceInfoLength  = 31,
   kMaxResourceInfoSize    = 32
};
