FileInputStream
GFileInputStream provides input streams that take their content from a file.
GFileInputStream implements #GSeekable, which allows the input stream to jump to arbitrary positions in the file, provided the filesystem of the file allows it. To find the position of a file input stream, use g_seekable_tell(). To find out if a file input stream supports seeking, use g_seekable_can_seek(). To position a file input stream, use g_seekable_seek().
Constructors
Functions
Tests if the length of the stream can be adjusted with g_seekable_truncate().
Clears the pending flag on @stream.
Closes the stream, releasing resources related to it.
Requests an asynchronous closes of the stream, releasing resources related to it. When the operation is finished @callback will be called. You can then call g_input_stream_close_finish() to get the result of the operation.
Finishes closing a stream asynchronously, started from g_input_stream_close_async().
Checks if an input stream has pending actions.
Queries a file input stream the given @attributes. This function blocks while querying the stream. For the asynchronous (non-blocking) version of this function, see g_file_input_stream_query_info_async(). While the stream is blocked, the stream will set the pending flag internally, and any other operations on the stream will fail with %G_IO_ERROR_PENDING.
Queries the stream information asynchronously. When the operation is finished @callback will be called. You can then call g_file_input_stream_query_info_finish() to get the result of the operation.
Finishes an asynchronous info query operation.
Like g_input_stream_read(), this tries to read @count bytes from the stream in a blocking fashion. However, rather than reading into a user-supplied buffer, this will create a new #GBytes containing the data that was read. This may be easier to use from language bindings.
Request an asynchronous read of @count bytes from the stream into a new #GBytes. When the operation is finished @callback will be called. You can then call g_input_stream_read_bytes_finish() to get the result of the operation.
Finishes an asynchronous stream read-into-#GBytes operation.
Finishes an asynchronous stream read operation.
Seeks in the stream by the given @offset, modified by @type.
Sets @stream to have actions pending. If the pending flag is already set or @stream is closed, it will return false and set
Tries to skip @count bytes from the stream. Will block during the operation.
Request an asynchronous skip of @count bytes from the stream. When the operation is finished @callback will be called. You can then call g_input_stream_skip_finish() to get the result of the operation.
Finishes a stream skip operation.
Sets the length of the stream to @offset. If the stream was previously larger than @offset, the extra data is discarded. If the stream was previously shorter than @offset, it is extended with NUL ('\0') bytes.
