glGetString — return a string describing the current GL connection

 

 

name

Specifies a symbolic constant, one of GL_EXTENSIONS, GL_RENDERER, GL_SHADING_LANGUAGE_VERSION, GL_VENDOR, or GL_VERSION. glGetStringi accepts only the GL_EXTENSIONS token.

index

For glGetStringi, specifies the index of the string to return.

glGetString returns a pointer to a static string describing some aspect of the current GL connection. name can be one of the following:

GL_EXTENSIONS

Returns the extension string supported by the implementation.

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

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.

If an error is generated, glGetString returns 0.

The client and server may support different versions. glGetString always returns a compatible version number. The release number always describes the server.

There is no defined relationship between the order in which extension names appear in the non-indexed string and the order in which they appear in the indexed query.

There is no defined relationship between any particular extension name and the index values; an extension name may correspond to a different index in different GL contexts and/or implementations.

GL_INVALID_ENUM is generated if name is not an accepted value.

GL_INVALID_VALUE is generated by glGetStringi if index is outside the valid range for indexed state name.
