Typedef Documentation

typedef struct OSRTStream OSRTStream

This structure is used to define a stream control block for keeping track of stream operations. A user may implement his own specific stream operations by defining read, skip, and close functions for input streams and write, flush, and close for output streams.

typedef long(* OSRTStreamBlockingReadProc)(struct OSRTStream *pStream, ASN1OCTET *pbuffer, size_t toReadBytes)

Stream blockingRead function pointer type. A user may implement a customized read function for specific input streams. The blockingRead function is defined in the OSRTStream control structure.

typedef int(* OSRTStreamCloseProc)(struct OSRTStream *pStream)

Pointer to stream close function. User may implement his own read function for any specific streams.

typedef int(* OSRTStreamFlushProc)(struct OSRTStream *pStream)

Pointer to stream flush function. User may implement his own read function for any specific output streams.

typedef int(* OSRTStreamMarkProc)(struct OSRTStream *pStream, size_t readAheadLimit)

Stream mark function pointer type. A user may implement a customized function for a specific input stream type. The mark function is defined in the OSRTStream control structure.

typedef long(* OSRTStreamReadProc)(struct OSRTStream *pStream, ASN1OCTET *pbuffer, size_t bufsize)

Pointer to stream read function. User may implement his own read function for any specific input streams.

typedef int(* OSRTStreamResetProc)(struct OSRTStream *pStream)

Stream reset function pointer type. A user may implement a customized function for a specific input stream type. The reset function is defined in the OSRTStream control structure.

typedef int(* OSRTStreamSkipProc)(struct OSRTStream *pStream, size_t skipBytes)

Stream skip function pointer type. A user may implement a customized function for a specific input stream type. The skip function is defined in the OSRTStream control structure.

typedef long(* OSRTStreamWriteProc)(struct OSRTStream *pStream, const ASN1OCTET *data, size_t numocts)

Pointer to stream write function. User may implement his own read function for any specific output streams.
