NAME
gluGetString - return a string describing the GLU version or GLU extensions
C SPECIFICATION
const GLubyte * gluGetString(GLenum name);
PARAMETERS
name Specifies a symbolic constant, one of GLU_VERSION, or GLU_EXTENSIONS.
DESCRIPTION
gluGetString returns a pointer to a static string describing the GLU version or the GLU extensions that are supported. The version number is one of the following forms: major_number.minor_numbermajor_number.minor_number.release_number. The version string is of the following form: version number<space>vendor-specific information Vendor-specific information is optional. Its format and contents depend on the implementation. The standard GLU contains a basic set of features and capabilities. If a company or group of companies wish to support other features, these may be included as extensions to the GLU. If name is GLU_EXTENSIONS, then gluGetString returns a space-separated list of names of supported GLU extensions. (Extension names never contain spaces.) All strings are null-terminated.
NOTES
gluGetString only returns information about GLU extensions. Call glGetString to get a list of GL extensions. gluGetString is an initialization routine. Calling it after a glNewList() results in undefined behavior.
ERRORS
NULL is returned if name is not GLU_VERSION or GLU_EXTENSIONS.
