glCheckFramebufferStatus - check the completeness status of a framebuffer
GLenum glCheckFramebufferStatus(GLenum target);
Specify the target of the framebuffer completeness check.
glCheckFramebufferStatus queries the completeness status of the framebuffer object
currently bound to target. target must be GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER or
GL_FRAMEBUFFER. GL_FRAMEBUFFER is equivalent to GL_DRAW_FRAMEBUFFER.
The return value is GL_FRAMEBUFFER_COMPLETE if the framebuffer bound to target is
complete. Otherwise, the return value is determined as follows:
o GL_FRAMEBUFFER_UNDEFINED is returned if target is the default framebuffer, but the
default framebuffer does not exist.
o GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT is returned if any of the framebuffer attachment
points are framebuffer incomplete.
o GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT is returned if the framebuffer does not
have at least one image attached to it.
o GL_FRAMEBUFFER_INCOMPLETE_DRAW_BUFFER is returned if the value of
GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is GL_NONE for any color attachment point(s)
named by GL_DRAWBUFFERi.
o GL_FRAMEBUFFER_INCOMPLETE_READ_BUFFER is returned if GL_READ_BUFFER is not GL_NONE and
the value of GL_FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is GL_NONE for the color attachment
point named by GL_READ_BUFFER.
o GL_FRAMEBUFFER_UNSUPPORTED is returned if the combination of internal formats of the
attached images violates an implementation-dependent set of restrictions.
o GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE is returned if the value of
GL_RENDERBUFFER_SAMPLES is not the same for all attached renderbuffers; if the value
of GL_TEXTURE_SAMPLES is the not same for all attached textures; or, if the attached
images are a mix of renderbuffers and textures, the value of GL_RENDERBUFFER_SAMPLES
does not match the value of GL_TEXTURE_SAMPLES.
o GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE is also returned if the value of
GL_TEXTURE_FIXED_SAMPLE_LOCATIONS is not the same for all attached textures; or, if
the attached images are a mix of renderbuffers and textures, the value of
GL_TEXTURE_FIXED_SAMPLE_LOCATIONS is not GL_TRUE for all attached textures.
o GL_FRAMEBUFFER_INCOMPLETE_LAYER_TARGETS is returned if any framebuffer attachment is
layered, and any populated attachment is not layered, or if all populated color
attachments are not from textures of the same target.
Additionally, if an error occurs, zero is returned.
GL_INVALID_ENUM is generated if target is not GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER or
