Functions
void *	glutGetProcAddress (const char *procName)

Detailed Description

Calling a library procedure directly can cause a link-time error if the feature does not exist. OpenGLUT provides a facility to query whether the feature exists, and provides a function-pointer for the feature, if present.

Function Documentation

void* glutGetProcAddress (  const char *  procName  )

Determine if an OpenGLUT feature or extension is available. Parameters: procName  Procedure name. Given a function name, searches for the function (or "procedure", hence "Proc") in internal tables. If the function is found, a pointer to the function is returned. If the function is not found, NULL is returned. In addition to an internal OpenGLUT table, this function will also consult glX (on X systems) or wgl (on WIN32 and WINCE), if the OpenGLUT tables do not have the requested function. It should return any OpenGL, glX, or wgl function if those functions are available. Note: The code makes no effort towards efficiency. It is advised that you cache the pointer retrieved from this function if you need a certain function repeatedly. See also: glXGetProcAddress(), wglGetProcAddress()
