GLUGETSTRING(3G) GLUGETSTRING(3G)

gluGetString - return a string describing the GLU version or GLU extensions

const GLubyte * gluGetString( GLenum name )












  

  
Specifies a symbolic constant, one of GLU_VERSION, or
      GLU_EXTENSIONS.










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_number
  

  major_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.








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.








NULL is returned if name is not GLU_VERSION or
    GLU_EXTENSIONS.
