glCheckFramebufferStatus — check the completeness status of a framebuffer
glCheckFramebufferStatus queries the completeness status of the framebuffer object currently bound to
target must be
GL_FRAMEBUFFER is equivalent to
The return value is
GL_FRAMEBUFFER_COMPLETE if the framebuffer bound to
target is complete. Otherwise,
the return value is determined as follows:
GL_FRAMEBUFFER_UNDEFINED is returned if
target is the default framebuffer, but the default framebuffer does not exist.
GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT is returned if any of the framebuffer attachment points are framebuffer incomplete.
GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT is returned if the framebuffer does not have at least one image attached to it.
GL_FRAMEBUFFER_INCOMPLETE_DRAW_BUFFER is returned if the value of
GL_NONE for any color attachment point(s) named by
GL_FRAMEBUFFER_INCOMPLETE_READ_BUFFER is returned if
GL_READ_BUFFER is not
and the value of
GL_NONE for the color attachment point named
GL_FRAMEBUFFER_UNSUPPORTED is returned if the combination of internal formats of the attached images violates
an implementation-dependent set of restrictions.
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_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE is also returned if the value of
not the same for all attached textures; or, if the attached images are a mix of renderbuffers and textures, the value of
GL_TRUE for all attached textures.
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
