Function
Giopollable_stream_read
since: 2.34
Declaration [src]
gssize
g_pollable_stream_read (
  GInputStream* stream,
  void* buffer,
  gsize count,
  gboolean blocking,
  GCancellable* cancellable,
  GError** error
)
Description [src]
Tries to read from stream, as with g_input_stream_read() (if
blocking is TRUE) or g_pollable_input_stream_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
GPollableInputStream for which g_pollable_input_stream_can_poll()
returns TRUE, or else the behavior is undefined. If blocking is
TRUE, then stream does not need to be a GPollableInputStream.

Parameters
- stream
- 
            Type: GInputStreamA GInputStream.The data is owned by the caller of the function. 
- buffer
- 
            Type: An array of guint8A buffer to read data into. The length of the array is specified in the countargument.The data is owned by the caller of the function. 
- count
- 
            Type: gsizeThe number of bytes to read. 
- blocking
- 
            Type: gbooleanWhether to do blocking I/O. 
- cancellable
- 
            Type: GCancellableOptional GCancellableobject,NULLto ignore.The argument can be NULL.The data is owned by the caller of the function. 
- error
- 
            Type: GError **The return location for a recoverable error. The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the function if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
