如何在OpenGL ES 2中加载函数？

Question

I searched for a long time and couldn't find any websites that describe how to do this. 我搜索了很长时间，找不到任何描述该操作方法的网站。

Is eglGetProcAddress the only function needed to do this? eglGetProcAddress是执行此操作所需的唯一功能吗？

I tried the following, but it didn't even compile: 我尝试了以下操作，但它甚至没有编译：

GLuint GL_APICALL GL_APIENTRY(*glCreateShader)(GLenum) = (GLuint GL_APICALL GL_APIENTRY(*)(GLenum))eglGetProcAddress("glCreateShader");

I also tried this, but the same error occured: 我也试过了，但是发生了同样的错误：

PFNGLCREATESHADERPROC glCreateShader = (PFNGLCREATESHADERPROC)eglGetProcAddress("glCreateShader");

Answer 1

我上面发布的代码是正确的，但是应该删除GLES / gl2.h文件的函数原型，并且应该以上述第二种方式声明函数。
