Function glGetString

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_SHADING_LANGUAGE_VERSION Returns a version or release number for the shading language.

glGetStringi returns a pointer to a static string indexed by index. name can be one of the following:

• GL_EXTENSIONS For glGetStringi only, returns the extension string supported by the implementation at index.

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.

The GL_VERSION and GL_SHADING_LANGUAGE_VERSION strings begin 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.

All strings are null-terminated.
