gInputStreamSkip: gInputStreamSkip
Description
Tries to skip count bytes from the stream. Will block during the operation.Usage
gInputStreamSkip(object, count, cancellable = NULL, .errwarn = TRUE)
Arguments
count
the number of bytes that will be skipped from the stream
.errwarn
Whether to issue a warning on error or fail silently
Value
A list containing the following elements:
- retval
- [integer] Number of bytes skipped, or -1 on error
error- location to store the error occuring, or
NULL to ignore
Details
This is identical to gInputStreamRead, 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.
