Very easy to test:
Code:
$> cat mach*
echo "1: $1"
echo "2: $2"
echo "3: $3"
echo "4: $4"
$> ./mach* red green 'dark !*red' blue
1: red
2: green
3: dark !*red
4: blue

glgetconvolutionfilter

GLGETCONVOLUTIONFILTER(3G)												GLGETCONVOLUTIONFILTER(3G)

NAME

       glGetConvolutionFilter - get current 1D or 2D convolution filter kernel

C SPECIFICATION

       void glGetConvolutionFilter( GLenum target,
				    GLenum format,
				    GLenum type,
				    GLvoid *image )

PARAMETERS

       target  The filter to be retrieved.  Must be one of GL_CONVOLUTION_1D or GL_CONVOLUTION_2D.

       format  Format of the output image.  Must be one of GL_RED, GL_GREEN, GL_BLUE, GL_ALPHA, GL_RGB, GL_BGR, GL_RGBA, GL_BGRA, GL_LUMINANCE, or
	       GL_LUMINANCE_ALPHA.

       type    Data type of components in the output image.  Symbolic constants GL_UNSIGNED_BYTE, GL_BYTE, GL_BITMAP, GL_UNSIGNED_SHORT, GL_SHORT,
	       GL_UNSIGNED_INT,     GL_INT,	GL_FLOAT,     GL_UNSIGNED_BYTE_3_3_2,	  GL_UNSIGNED_BYTE_2_3_3_REV,	  GL_UNSIGNED_SHORT_5_6_5,
	       GL_UNSIGNED_SHORT_5_6_5_REV,	  GL_UNSIGNED_SHORT_4_4_4_4,	   GL_UNSIGNED_SHORT_4_4_4_4_REV,	GL_UNSIGNED_SHORT_5_5_5_1,
	       GL_UNSIGNED_SHORT_1_5_5_5_REV,	  GL_UNSIGNED_INT_8_8_8_8,     GL_UNSIGNED_INT_8_8_8_8_REV,	GL_UNSIGNED_INT_10_10_10_2,    and
	       GL_UNSIGNED_INT_2_10_10_10_REV are accepted.

       image   Pointer to storage for the output image.

DESCRIPTION

       glGetConvolutionFilter returns the current 1D or 2D convolution filter kernel as an image.  The one- or two-dimensional image is placed	in
       image according to the specifications in format and type.  No pixel transfer operations are performed on this image, but the relevant pixel
       storage modes are applied.

       Color components that are present in format but not included in the internal  of the filter are	returned  as  zero.   The  assignments	of
       internal color components to the components of format are as follows.

							-----------------------------------------
							Internal Component   Resulting Component
							-----------------------------------------
							Red		     Red
							Green		     Green
							Blue		     Blue
							Alpha		     Alpha
							Luminance	     Red
							Intensity	     Red
							-----------------------------------------

NOTES

       glGetConvolutionFilter is present only if GL_ARB_imaging is returned when glGetString is called with an argument of GL_EXTENSIONS.

       The current separable 2D filter must be retrieved with glGetSeparableFilter rather than glGetConvolutionFilter.

ERRORS

       GL_INVALID_ENUM is generated if target is not one of the allowable values.

       GL_INVALID_ENUM is generated if format is not one of the allowable values.

       GL_INVALID_ENUM is generated if type is not one of the allowable values.

       GL_INVALID_OPERATION is generated if glGetConvolutionFilter is executed between the execution of glBegin and the corresponding execution of
       glEnd.

       GL_INVALID_OPERATION is generated if  type  is  one  of	GL_UNSIGNED_BYTE_3_3_2,  GL_UNSIGNED_BYTE_2_3_3_REV,  GL_UNSIGNED_SHORT_5_6_5,	or
       GL_UNSIGNED_SHORT_5_6_5_REV and format is not GL_RGB.

       GL_INVALID_OPERATION  is  generated  if type is one of GL_UNSIGNED_SHORT_4_4_4_4, GL_UNSIGNED_SHORT_4_4_4_4_REV, GL_UNSIGNED_SHORT_5_5_5_1,
       GL_UNSIGNED_SHORT_1_5_5_5_REV,	    GL_UNSIGNED_INT_8_8_8_8,	   GL_UNSIGNED_INT_8_8_8_8_REV,       GL_UNSIGNED_INT_10_10_10_2,	or
       GL_UNSIGNED_INT_2_10_10_10_REV and format is neither GL_RGBA nor GL_BGRA.
