If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glUseProgram() directly.

Since

v2.0.0

local ccGLUseProgram

(

local

program)

Uses the GL program in case program is different than the current one.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glUseProgram() directly.

Since

v2.0.0

void CC_DLL cocos2d::ccGLBlendFunc	(	GLenum	sfactor,
