NAME

     cfilutil -- Tool to exercise the content filter subsystem.

SYNOPSIS

     cfilutil [-hilqsv] -u unit [-a offset] [-d offset value] [-k increment] [-m length] [-p offset] [-r random] [-t delay]

DESCRIPTION

     Use cfilutil to exercise the content filter subsystem.

     The flags have the following meaning:

     -a offset
	      Auto start filtering with given offset.

     -a offset value
	      Default values for offset passin, peekin, passout, peekout, pass or peek.

     -h       Display this help.

     -i       Interactive mode.

     -k increment
	      Peek mode with increment.

     -l       Pass loopback traffic.

     -m length
	      Maximum dump length.

     -p offset
	      Pass mode (all or after given offset if it is > 0).

     -q       Decrease verbosity.

     -r rate  Random drop rate.

     -s       display content filter statistics (all, sock, filt, cfil).

     -t delay
	      Pass delay in microseconds.

     -u unit  NECP filter control unit.

     -v       Increase verbosity.

NAME

       glInvalidateBufferSubData - invalidate a region of a buffer object's data store

C SPECIFICATION

       void glInvalidateBufferSubData(GLuint buffer, GLintptr offset, GLsizeiptr length);

PARAMETERS

       buffer
	   The name of a buffer object, a subrange of whose data store to invalidate.

       offset
	   The offset within the buffer's data store of the start of the range to be invalidated.

       length
	   The length of the range within the buffer's data store to be invalidated.

DESCRIPTION

       glInvalidateBufferSubData invalidates all or part of the content of the data store of a buffer object. After invalidation, the content of
       the specified range of the buffer's data store becomes undefined. The start of the range is given by offset and its size is given by
       length, both measured in basic machine units.

ERRORS

       GL_INVALID_VALUE is generated if offset or length is negative, or if offset + length is greater than the value of GL_BUFFER_SIZE for
       buffer.

       GL_INVALID_VALUE is generated if buffer is not the name of an existing buffer object.

       GL_INVALID_OPERATION is generated if any part of buffer is currently mapped.

ASSOCIATED GETS

       glGetBufferParameter() with argument GL_BUFFER_SIZE
