NAME
       glGetProgramEnvParameterfvARB,glGetProgramEnvParameterdvARB  -  Returns
       the value of a environment program parameter.

C SPECIFICATION
       void glGetProgramEnvParameterfvARB( GLenum target,
					   GLuint index,
					   GLfloat *params)
       void glGetProgramEnvParameterdvARB( GLenum target,
					   GLuint index,
					   GLdouble *params)

PARAMETERS
       target Specifies the program object to be queried accepted values are:															       GL_VER‐
																								       TEX_PRO‐
																								       GRAM_ARB
																								       and
																								       GL_FRAG‐
																								       MENT_PRO‐
																								       GRAM_ARB.

       index Specifies the environment parameter to be queried.

       params Returns the value of the specified environment parameter.

DESCRIPTION
       glGetProgramEnvParameterARB  returns  the current value for the program
       environment parameter numbered index belonging to  the  program	object
       currently  bound	 to  target,  and  places the information in the array
       params.

       When the program target type is VERTEX_PROGRAM_ARB, each program	 envi‐
       ronment parameter returned is an array of four values.

ERRORS
       GL_INVALID_ENUM	is generated if target specifies a nonexistent program
       target or a program target that does not	 support  program  environment
       parameters.

       GL_INVALID_VALUE	 is generated if index is greater than or equal to the
       implementation-dependent number of supported program environment param‐
       eters for the program target.

       GL_INVALID_ENUM	is generated if target is not GL_VERTEX_PROGRAM_ARB or
       GL_FRAGMENT_PROGRAM_ARB.
