Functions |
| int | rtxStreamClose (OSCTXT *pctxt) |
| | This function closes the input or output stream and releases any system resources associated with the stream.
|
| int | rtxStreamFlush (OSCTXT *pctxt) |
| | This function flushes the output stream and forces any buffered output octets to be written out.
|
| int | rtxStreamInit (OSCTXT *pctxt) |
| | This function initializes a stream part of the context block.
|
| long | rtxStreamRead (OSCTXT *pctxt, OSOCTET *pbuffer, size_t bufSize) |
| | This function reads up to 'bufsize' bytes of data from the input stream into an array of octets.
|
| long | rtxStreamBlockingRead (OSCTXT *pctxt, OSOCTET *pbuffer, size_t readBytes) |
| | This function reads up to 'bufsize' bytes of data from the input stream into an array of octets.
|
| int | rtxStreamSkip (OSCTXT *pctxt, size_t skipBytes) |
| | This function skips over and discards the specified amount of data octets from this input stream.
|
| long | rtxStreamWrite (OSCTXT *pctxt, const OSOCTET *data, size_t numocts) |
| | This function writes the specified amount of octets from the specified array to the output stream.
|
| int | rtxStreamGetIOBytes (OSCTXT *pctxt, size_t *pPos) |
| | This function returns the number of processed octets.
|
| int | rtxStreamMark (OSCTXT *pctxt, size_t readAheadLimit) |
| | Marks the current position in this input stream.
|
| int | rtxStreamReset (OSCTXT *pctxt) |
| | Repositions this stream to the position recorded by the last call to the rtxStreamMark function.
|
| OSBOOL | rtxStreamMarkSupported (OSCTXT *pctxt) |
| | Tests if this input stream supports the mark and reset methods.
|
| OSBOOL | rtxStreamIsOpened (OSCTXT *pctxt) |
| | Tests if this stream opened (for reading or writing).
|
| OSBOOL | rtxStreamIsReadable (OSCTXT *pctxt) |
| | Tests if this stream opened for reading.
|
| OSBOOL | rtxStreamIsWritable (OSCTXT *pctxt) |
| | Tests if this stream opened for riting.
|
| int | rtxStreamRelease (OSCTXT *pctxt) |
| | This function releases the stream's resources.
