NAMEglInvalidateSubFramebuffer, glInvalidateNamedFramebufferSubData − invalidate the content of a region of some or all of a framebuffer's attachments

C SPECIFICATIONvoid glInvalidateSubFramebuffer(GLenum target, GLsizei numAttachments, const GLenum * attachments, GLint x, GLint y, GLint width, GLint height); void glInvalidateNamedFramebufferSubData(GLuint framebuffer, GLsizei numAttachments, const GLenum *attachments, GLint x, GLint y, GLsizei width, GLsizei height);

PARAMETERStarget Specifies the target to which the framebuffer object is attached for glInvalidateSubFramebuffer​. framebuffer Specifies the name of the framebuffer object for glInvalidateNamedFramebufferSubData​. numAttachments Specifies the number of entries in the attachments array​. attachments Specifies a pointer to an array identifying the attachments to be invalidated​. x Specifies the X offset of the region to be invalidated​. y Specifies the Y offset of the region to be invalidated​. width Specifies the width of the region to be invalidated​. height Specifies the height of the region to be invalidated​.

DESCRIPTIONglInvalidateSubFramebuffer and glInvalidateNamedFramebufferSubData invalidate the contents of a specified region of a specified set of attachments of a framebuffer​. For glInvalidateSubFramebuffer, the framebuffer object is that bound to target, which must be one of GL_FRAMEBUFFER, GL_READ_FRAMEBUFFER or GL_DRAW_FRAMEBUFFER​. GL_FRAMEBUFFER is equivalent to GL_DRAW_FRAMEBUFFER​. Default framebuffers may also be invalidated if bound to target​. For glInvalidateNamedFramebufferSubData, framebuffer is the name of the framebuffer object​. If framebuffer is zero, the default draw framebuffer is affected​. The set of attachments of which a region is to be invalidated are specified in the attachments array, which contains numAttachments elements​. If the specified framebuffer is a framebuffer object, each element of attachments must be one of GL_DEPTH_ATTACHMENT, GL_STENCIL_ATTACHMENT GL_DEPTH_STENCIL_ATTACHMENT, or GL_COLOR_ATTACHMENTi, where i is between zero and the value of GL_MAX_FRAMEBUFFER_ATTACHMENTS minus one​. If the specified framebuffer is a default framebuffer, each element of attachments must be one of GL_FRONT_LEFT, GL_FRONT_RIGHT, GL_BACK_LEFT, GL_BACK_RIGHT, GL_AUXi, GL_ACCUM, GL_COLOR, GL_DEPTH, or GL_STENCIL​. GL_COLOR, is treated as GL_BACK_LEFT for a double−buffered context and GL_FRONT_LEFT for a single−buffered context​. The other attachments identify the corresponding specific buffer​. The contents of the specified region of each specified attachment become undefined after execution of glInvalidateSubFramebuffer or glInvalidateNamedFramebufferSubData​. The region to be invalidated is specified by x, y, width and height where x and y give the offset from the origin (with lower−left corner at $(0,0)$) and width and height are the width and height, respectively, of the region​. Any pixels lying outside of the window allocated to the current GL context (for the default framebuffer), or outside of the attachments of the framebuffer object, are ignored​. If the framebuffer object is not complete, these commands may be ignored​. If the framebuffer object is not complete, glInvalidateSubFramebuffer and glInvalidateNamedFramebufferSubData may be ignored​. This is not an error​.

ERRORSGL_INVALID_ENUM by glInvalidateSubFramebuffer if target is not one of the accepted framebuffer targets​. GL_INVALID_OPERATION by glInvalidateNamedFramebufferSubData if framebuffer is not zero of the name of an existing framebuffer object​. GL_INVALID_VALUE is generated if numAttachments, width or height is negative​. GL_INVALID_ENUM is generated if any element of attachments is not one of the accepted framebuffer attachment points, as described above​. GL_INVALID_OPERATION is generated if element of attachments is GL_COLOR_ATTACHMENTm where m is greater than or equal to the value of GL_MAX_COLOR_ATTACHMENTS​.
