glGetString

glGetString: return a string describing the current GL connection.
C Specification
constGLubyte *glGetString(
Parameters
name
Description
glGetString returns a pointer to a static string describing some aspect of the current GL
connection. name can be one of the following:
GL_VENDOR
Returns the company responsible for this GL implementation. This name does not
change from release to release.
GL_RENDERER
Returns the name of the renderer. This name is typically specific to a particular
configuration of a hardware platform. It does not change from release to release.
GL_VERSION
Returns a version or release number.
GL_EXTENSIONS
Returns a space-separated list of supported extensions to GL.
Because the GL does not include queries for the performance characteristics of an
implementation, some applications are written to recognize known platforms and modify
their GL usage based on known performance characteristics of these platforms. Strings
GL_VENDOR and GL_RENDERER together uniquely specify a platform. They do not
change from release to release and should be used by platform-recognition algorithms.
Some applications want to make use of features that are not part of the standard GL.
These features may be implemented as extensions to the standard GL. The
GL_EXTENSIONS string is a space-separated list of supported GL extensions.
(Extension names never contain a space character.)
The GL_VERSION string begins with a version number. The version number uses one of
these forms:
<major_number>.<minor_number>
<major_number>.<minor_number>.<release_number>
Vendor-specific information may follow the version number. Its format depends on the
implementation, but a space always separates the version number and the
vendor-specific information.
