NAME

6       glGetString - return a string describing the current GL connection
7

C SPECIFICATION

9       const GLubyte* glGetString(GLenum name);
10

C SPECIFICATION

12       const GLubyte* glGetStringi(GLenum name, GLuint index);
13

PARAMETERS

15       name
16           Specifies a symbolic constant, one of GL_VENDOR, GL_RENDERER,
17           GL_VERSION, or GL_SHADING_LANGUAGE_VERSION. Additionally,
18           glGetStringi accepts the GL_EXTENSIONS token.
19
20       index
21           For glGetStringi, specifies the index of the string to return.
22

DESCRIPTION

24       glGetString returns a pointer to a static string describing some aspect
25       of the current GL connection.  name can be one of the following:
26
27       GL_VENDOR
28
29           Returns the company responsible for this GL implementation. This
30           name does not change from release to release.
31
32       GL_RENDERER
33
34           Returns the name of the renderer. This name is typically specific
35           to a particular configuration of a hardware platform. It does not
36           change from release to release.
37
38       GL_VERSION
39
40           Returns a version or release number.
41
42       GL_SHADING_LANGUAGE_VERSION
43
44           Returns a version or release number for the shading language.
45
46       glGetStringi returns a pointer to a static string indexed by index.
47       name can be one of the following:
48
49       GL_EXTENSIONS
50
51           For glGetStringi only, returns the extension string supported by
52           the implementation at index.
53
54       Strings GL_VENDOR and GL_RENDERER together uniquely specify a platform.
55       They do not change from release to release and should be used by
56       platform-recognition algorithms.
57
58       The GL_VERSION and GL_SHADING_LANGUAGE_VERSION strings begin with a
59       version number. The version number uses one of these forms:
60
61       major_number.minor_numbermajor_number.minor_number.release_number
62
63       Vendor-specific information may follow the version number. Its format
64       depends on the implementation, but a space always separates the version
65       number and the vendor-specific information.
66
67       All strings are null-terminated.
68

NOTES

70       If an error is generated, glGetString returns 0.
71
72       The client and server may support different versions.  glGetString
73       always returns a compatible version number. The release number always
74       describes the server.
75

ERRORS

77       GL_INVALID_ENUM is generated if name is not an accepted value.
78
79       GL_INVALID_VALUE is generated by glGetStringi if index is outside the
80       valid range for indexed state name.
