glGetRenderbufferParameteriv 3G
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.
