This software +_C_ was created using the OpenGL(R) version 1.2.1 Sample Implementation +_C_ published by SGI, but has not been independently verified as being +_C_ compliant with the OpenGL(R) version 1.2.1 Specification. +_C_ +_C_ The first character in this file must be an '_'! +_C_ Anything on a line after _C_ is ignored +_define(_filters,eqn)_C_ +_C_ eqn is automatically replaced with neqn for nroff +_header(GetString, return a string describing the current GL connection) +_names(GetString) +.SH PARAMETERS +_phead(_param1) +Specifies a symbolic constant, one of +_const(VENDOR), _const(RENDERER), _const(VERSION), or _const(EXTENSIONS). +.SH DESCRIPTION +_cmnd returns a pointer to a static string +describing some aspect of the current GL connection. +_param1 can be one of the following: +.TP 20 +_const(VENDOR) +Returns the company responsible for this GL implementation. +This name does not change from release to release. +.TP +_const(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. +.TP +_const(VERSION) +Returns a version or release number. +.TP +_const(EXTENSIONS) +Returns a space-separated list of supported extensions to GL. +.P +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 _const(VENDOR) and _const(RENDERER) together uniquely specify +a platform. They do not change from release to release and should be used +by platform-recognition algorithms. +.P +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 _const(EXTENSIONS) string is a space-separated +list of supported GL extensions. +(Extension names never contain a space character.) +.P +The _const(VERSION) string begins with a version number. +The version number uses one +of these forms: +.P +\f2major_number.minor_number\fP +.br +\f2major_number.minor_number.release_number\fP +.P +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. +.P +All strings are null-terminated. +.SH NOTES +If an error is generated, _cmnd returns 0. +.P +The client and server may support different versions or extensions. +_cmnd always returns a compatible version number or list of extensions. +The release number always describes the server. +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 is not an accepted value. +.P +_const(INVALID_OPERATION) is generated if _cmnd +is executed between the execution of _cmnd(Begin) +and the corresponding execution of _cmnd(End). -- cgit v1.2.3
