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.
