BrlAPI handles - Typedefs typedef struct brlapi_handle_t brlapi_handle_t Functions size_t BRLAPI_STDCALL brlapi_getHandleSize (void) Detailed Description Each function provided by BrlAPI comes in two versions. 1. A version whose name is prefixed by brlapi_ for clients opening only one simultaneous connection with BrlAPI (most frequen case) 2. A version whose name is prefixed by brlapi__ for use by clients wishing to open more than one connection to BrlAPI. A function called brlapi__foo is used in exactly the same way as its brlapi_foo counterpart, except that it takes an additional argument (the first one), which is a handle letting the client refer to a given connection in a similar manner to what file descriptors do. In case you want to check that your code is not erroneously using brlapi_foo functions, define BRLAPI_NO_SINGLE_SESSION before including <brlapi.h>: that will disable the declaration of all single session functions. Typedef Documentation typedef struct brlapi_handle_t brlapi_handle_t Type for BrlAPI hanles Function Documentation size_t BRLAPI_STDCALL brlapi_getHandleSize (void) Returns the size of an object of type brlapi_handle_t in bytes Author Generated automatically by Doxygen for BrlAPI from the source code.
