Type Alias GErrorCopyFunc

pub type GErrorCopyFunc = Option<unsafe extern "C" fn(src_error: *const GError, dest_error: *mut GError)>;

GErrorCopyFunc: @src_error: source extended error @dest_error: destination extended error

Specifies the type of function which is called when an extended error instance is copied. It is passed the pointer to the destination error and source error, and should copy only the fields of the private data from @src_error to @dest_error.

Normally, it is better to use G_DEFINE_EXTENDED_ERROR(), as it already takes care of getting the private data from @src_error and @dest_error.
