ios - swift glGetProgramInfoLog

Question

有谁知道如何快速实现这个？整个函数调用是

glGetProgramInfoLog(
  <#program: GLuint#>, 
  <#bufsize: GLsizei#>, 
  <#length: UnsafeMutablePointer<GLsizei>#>, 
  <#infolog: UnsafeMutablePointer<GLchar>#>)

我理解传递指针而不是缓冲区大小。安卓根本就没有这些参数。

Answer 1

对于任何寻找答案的人，您可以使用以下代码:

程序在哪里 let program = glCreateProgram()

swift 2

var message = [CChar](count: 256, repeatedValue: CChar(0))
var length = GLsizei(0)
glGetProgramInfoLog(program, 256, &length, &message)
print(String(UTF8String: message))

swift 3

var message = [CChar](repeating: CChar(0), count: 256)
var length = GLsizei(0)
glGetProgramInfoLog(program, 256, &length, &message)
var s = String.init(utf8String: message)!
if(s.characters.count > 0){print("Shader compile log: \(s)")} //only prints if log isnt empty
