GLuint shader,
mgString& logStr)
{
GLint logLen, retLen;
glGetShaderiv(shader, GL_INFO_LOG_LENGTH, &logLen);
char* logText = new char[logLen];

logStr.empty();
logStr.write(logText, retLen);
delete logText;
}示例2: glGetShaderiv
//--------------------------------------------------------------------------
// return shader log error messages as a string

}示例3: parseVar
//--------------------------------------------------------------
// parse a name or value off the strings
