NAME

       glGetMultisamplefv - retrieve the location of a sample

C SPECIFICATION

       void glGetMultisamplefv(GLenum pname, GLuint index, GLfloat *val);

PARAMETERS

       pname
           Specifies the sample parameter name.  pname must be GL_SAMPLE_POSITION.

       index
           Specifies the index of the sample whose position to query.

       val
           Specifies the address of an array to receive the position of the sample.

DESCRIPTION

       glGetMultisamplefv queries the location of a given sample.  pname specifies the sample parameter to
       retrieve and must be GL_SAMPLE_POSITION.  index corresponds to the sample for which the location should
       be returned. The sample location is returned as two floating-point values in val[0] and val[1], each
       between 0 and 1, corresponding to the x and y locations respectively in the GL pixel space of that
       sample. (0.5, 0.5) this corresponds to the pixel center.  index must be between zero and the value of
       GL_SAMPLES minus one.

       If the multisample mode does not have fixed sample locations, the returned values may only reflect the
       locations of samples within some pixels.

ERRORS

       GL_INVALID_ENUM is generated if pname is not one GL_SAMPLE_POSITION.

       GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_SAMPLES.
