nb_available(stream)
Returns the number of bytes available for reading before a read from this stream or buffer will block.

-
Check available bytes in a file stream:
- First, we open a file stream using
openfunction and specify the file name and mode ("r" for reading). - Then, we pass the stream to
nb_availablefunction to get the number of available bytes for reading. - Finally, we print the result.
- It's important to close the stream using
closefunction after we are done with it.
- First, we open a file stream using
- Check available bytes in a buffer:
- We create an
IOBufferusingIOBuffer("Hello, World!"), which initializes the buffer with the given string. - Then, we pass the buffer to
nb_availablefunction to get the number of available bytes for reading. - Finally, we print the result.
- We create an
Please note that the nb_available function is typically used with stream-like objects, such as file streams or buffers.
