What about this google (OpenGL reference) result?

Note that the base name for such methods is glUniform, so look for that. 1f means one float parameter, ARB means the method is common but not part of core OpenGL as of some version. I'm not sure in which exact version the function was promoted, but I assume it was something around 3.0, and thus you'd now just use glUniform1f.

Edit: The spec sais promotion happend in 2.0: "glUniform is available only if the GL version is 2.0 or greater."
