Virtual Method
GioInputStreamskip
Declaration
gssize
skip (
GInputStream* stream,
gsize count,
GCancellable* cancellable,
GError** error
)
Description
Tries to skip count bytes from the stream. Will block during the operation.
This is identical to g_input_stream_read(), from a behaviour standpoint, but the bytes that are skipped are not returned to the user. Some streams have an implementation that is more efficient than reading the data.
This function is optional for inherited classes, as the default implementation emulates it using read.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.
Parameters
count-
Type:
gsizeThe number of bytes that will be skipped from the stream.
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 left initialized to NULLby the virtual 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.
