BUGLE-ERROR(7) Bugle user manual BUGLE-ERROR(7)NAMEbugle-error - detect errors in OpenGL calls
SYNOPSIS
filterset error
DESCRIPTION
This filter-set does not take any visible action on its own, but
provides a service to other filter-sets. It calls glGetError(3) after
every OpenGL call to detect OpenGL errors (it does not detect X
errors).
Usually you will not need to explicitly load this filter-set; if you
want to be informed of OpenGL errors, either use the showerror
filterset, or gldb-gui(1). However, you may occasionally see the
message
An OpenGL error was detected but will be lost to the application.
This means that bugle´s internal error-checking code accidentally
collected an error caused by one of your calls, and thus if your
application later called glGetError(3) it would not be informed of the
error. However, if you add the error filter-set, it will catch the
error first and your application will be correctly informed of the
error.
BUGS
Because the error reporting semantics of OpenGL are not completely
defined (in particular, an implementation may choose how many error
flags it has), it is impossible to guarantee that this filter-set is
completely transparent to the application. However, the first call to
glGetError(3) always return an error, and in practice this is all that
is necessary.
