pollable_stream_read
Description:
[ Version ( since = "2.34" ) ]
public ssize_t pollable_stream_read (InputStream stream, uint8[] buffer, bool blocking, Cancellable? cancellable = null) throws Error
Tries to read from stream, as with read (if
blocking is true) or
read_nonblocking (if blocking is
false).
This can be used to more easily share code between blocking and non-blocking implementations of a method.
If blocking is false, then stream must be a
PollableInputStream for which
can_poll returns true,
or else the behavior is undefined. If blocking is true, then stream does not need to
be a PollableInputStream.
Parameters:
| stream | |
| buffer |
a buffer to read data into |
| blocking |
whether to do blocking I/O |
| cancellable |
optional Cancellable object, null to ignore. |
| count |
the number of bytes to read |
Returns:
|
the number of bytes read, or -1 on error. |
