glEnableGLARBdrawinstanced

glEnable is a function in the OpenGL graphics API used to enable various capabilities of the OpenGL state machine. One specific capability that can be enabled is GL_ARBD. This identifier is associated with the ARB_debug_output extension. When GL_ARBD is enabled, it allows an application to receive debug messages generated by the OpenGL driver. These messages can provide valuable information about potential issues, performance problems, or invalid API usage.

The glEnable function takes a single argument, which is the symbolic constant representing the capability to be enabled. In this case, the constant is GL_ARBD. Calling glEnable(GL_ARBD) activates the debug output functionality. Once enabled, applications can then register callback functions that will be invoked whenever the OpenGL driver generates a debug message. These messages can range from notifications and warnings to errors, aiding developers in identifying and resolving problems within their graphics applications. Disabling this capability is typically done using glDisable(GL_ARBD).
