|
|
\func{}{wxInputStream}{\void}
|
|
|
|
Creates a dummy input stream.
|
|
|
|
\func{}{wxInputStream}{\param{wxStreamBuffer *}{sbuf}}
|
|
|
|
Creates an input stream using the specified stream buffer \it{sbuf}. This
|
|
stream buffer can point to another stream.
|
|
|

\membersection{wxInputStream::Peek}
|
|
|
|
\func{char}{Peek}{\void}
|
|
|
|
Returns the first character in the input queue without removing it.
|
|
|
|
\membersection{wxInputStream::GetC}
|
|
|
|
\func{char}{GetC}{\void}
|
|
|
|
Returns the first character in the input queue and removes it.
|
|
|
|
\membersection{wxInputStream::Read}
|
|
|
|
\func{wxInputStream\&}{Read}{\param{void *}{buffer}, \param{size_t}{ size}}
|
|
|
|
Reads the specified amount of bytes and stores the data in \it{buffer}.
|
|
|
|
\wxheading{Warning}
|
|
|
|
The buffer absolutely needs to have at least the specified size.
|
|
|
|
\wxheading{Return value}
|
|
|
|
This function returns a reference on the current object, so the user can test
|
|
any states of the stream right away.
|
|
|
|
\func{wxInputStream\&}{Read}{\param{wxOutputStream\&}{ stream_out}}
|
|
|
|
Reads data from the input queue and stores it in the specified output stream.
|
|
The data is read until an error is raised by one of the two streams.
|
|
|
|
\wxheading{Return value}
|
|
|
|
This function returns a reference on the current object, so the user can test
|
|
any states of the stream right away.
