NAME¶
glGetString - return a string describing the current GL connection
C SPECIFICATION¶
const GLubyte *glGetString(GLenum name);
const GLubyte *glGetStringi(GLenum name, GLuint index);
PARAMETERS¶
name
index
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
GL_RENDERER
GL_VERSION
GL_SHADING_LANGUAGE_VERSION
glGetStringi returns a pointer to a static string indexed by index. name can be one of the following:
GL_EXTENSIONS
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.
NOTES¶
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.
ERRORS¶
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.
