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.
