ARBcreatecontext is a function introduced to the OpenGL specification in version 3.2 that allows applications to request the creation of a new OpenGL context with specific attributes. The function was added to provide developers with finer control over the features and capabilities of rendering contexts, such as version number, debug flags, and robustness options, which were not available through the operating system's native context‑creation APIs in earlier versions.
The API signature is defined as follows:
void ARBcreatecontext(ARB_context *ctx, int *attribList)
The first argument is a pointer to a context object that will be initialized by the function.
Internal behavior of ARBcreatecontext is implemented by the driver layer. When invoked, the function queries the

In summary, ARBcreatecontext provides a standardized, extension‑free mechanism for requesting an OpenGL context with precise attributes,
