Method

GioSeekabletruncate

Declaration

gboolean
g_seekable_truncate (
  GSeekable* seekable,
  goffset offset,
  GCancellable* cancellable,
  GError** error
)

Description

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.

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

offset goffset
 

New length for seekable, in bytes.

cancellable GCancellable
 

Optional GCancellable object, NULL to ignore.

 The argument can be NULL.
 The data is owned by the caller of the function.
error GError **
  The return location for a GError*, or NULL.

Return value

Returns: gboolean
 

TRUE if successful. If an error has occurred, this function will return FALSE and set error appropriately if present.
