GLRENDERBUFFERSTORAG(3G) [FIXME: manual] GLRENDERBUFFERSTORAG(3G) NAME
glRenderbufferStorage - establish data storage, format and dimensions of a renderbuffer object's image C SPECIFICATION
void glRenderbufferStorage(GLenum target, GLenum internalformat, GLsizei width, GLsizei height); PARAMETERS
target Specifies a binding to which the target of the allocation and must be GL_RENDERBUFFER. internalformat Specifies the internal format to use for the renderbuffer object's image. width Specifies the width of the renderbuffer, in pixels. height Specifies the height of the renderbuffer, in pixels. DESCRIPTION
glRenderbufferStorage is equivalent to calling glRenderbufferStorageMultisample() with the samples set to zero. The target of the operation, specified by target must be GL_RENDERBUFFER. internalformat specifies the internal format to be used for the renderbuffer object's storage and must be a color-renderable, depth-renderable, or stencil-renderable format. width and height are the dimensions, in pixels, of the renderbuffer. Both width and height must be less than or equal to the value of GL_MAX_RENDERBUFFER_SIZE. Upon success, glRenderbufferStorage deletes any existing data store for the renderbuffer image and the contents of the data store after calling glRenderbufferStorage are undefined. ERRORS
GL_INVALID_ENUM is generated if target is not GL_RENDERBUFFER. GL_INVALID_VALUE is generated if either of width or height is negative, or greater than the value of GL_MAX_RENDERBUFFER_SIZE. GL_INVALID_ENUM is generated if internalformat is not a color-renderable, depth-renderable, or stencil-renderable format. GL_OUT_OF_MEMORY is generated if the GL is unable to create a data store of the requested size. SEE ALSO

GLGETRENDERBUFFERPAR(3G) [FIXME: manual] GLGETRENDERBUFFERPAR(3G) NAME
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
