glGetRenderbufferParameteriv - retrieve information about a bound renderbuffer object C SPECIFICATION
void glGetRenderbufferParameteriv(GLenum target, GLenum pname, GLint *params); PARAMETERS
target Specifies the target of the query operation. target must be GL_RENDERBUFFER. pname Specifies the parameter whose value to retrieve from the renderbuffer bound to target. params Specifies the address of an array to receive the value of the queried parameter. DESCRIPTION
glGetRenderbufferParameteriv retrieves information about a bound renderbuffer object. target specifies the target of the query operation and must be GL_RENDERBUFFER. pname specifies the parameter whose value to query and must be one of GL_RENDERBUFFER_WIDTH, GL_RENDERBUFFER_HEIGHT, GL_RENDERBUFFER_INTERNAL_FORMAT, GL_RENDERBUFFER_RED_SIZE, GL_RENDERBUFFER_GREEN_SIZE, GL_RENDERBUFFER_BLUE_SIZE, GL_RENDERBUFFER_ALPHA_SIZE, GL_RENDERBUFFER_DEPTH_SIZE, GL_RENDERBUFFER_DEPTH_SIZE, GL_RENDERBUFFER_STENCIL_SIZE, or GL_RENDERBUFFER_SAMPLES. Upon a successful return from glGetRenderbufferParameteriv, if pname is GL_RENDERBUFFER_WIDTH, GL_RENDERBUFFER_HEIGHT, GL_RENDERBUFFER_INTERNAL_FORMAT, or GL_RENDERBUFFER_SAMPLES, then params will contain the width in pixels, the height in pixels, the internal format, or the number of samples, respectively, of the image of the renderbuffer currently bound to target. If pname is GL_RENDERBUFFER_RED_SIZE, GL_RENDERBUFFER_GREEN_SIZE, GL_RENDERBUFFER_BLUE_SIZE, GL_RENDERBUFFER_ALPHA_SIZE, GL_RENDERBUFFER_DEPTH_SIZE, or GL_RENDERBUFFER_STENCIL_SIZE, then params will contain the actual resolutions (not the resolutions specified when the image array was defined) for the red, green, blue, alpha depth, or stencil components, respectively, of the image of the renderbuffer currently bound to target. ERRORS
GL_INVALID_ENUM is generated if pname is not one of the accepted tokens. SEE ALSO
