Functions

◆ abort()

void QDisabledNetworkReply::abort ( )
inlinevirtual

Aborts the operation immediately and close down any network connections still open.

Uploads still in progress are also aborted.

See also
close()

Implements QNetworkReply.

Definition at line 232 of file qnetworkreplyimpl_p.h.

232 { }

◆ readData()

qint64 QDisabledNetworkReply::readData ( char *  data,
qint64  maxSize 
)
inlineprotectedvirtual

Reads up to maxSize bytes from the device into data, and returns the number of bytes read or -1 if an error occurred.

If there are no bytes to be read and there can never be more bytes available (examples include socket closed, pipe closed, sub-process finished), this function returns -1.

This function is called by QIODevice. Reimplement this function when creating a subclass of QIODevice.

When reimplementing this function it is important that this function reads all the required data before returning. This is required in order for QDataStream to be able to operate on the class. QDataStream assumes all the requested information was read and therefore does not retry reading if there was a problem.

Implements QIODevice.
