How do I get this extra pointer ? :D
The C code is:
char *file;
shader = glCreateShader(GL_FRAGMENT_SHADER);
file = textFileRead("program.frag");
const char * filep = file;
glShaderSource(f, 1, &filep,NULL);
free(filep);
my D attempt:
char[] file;
GLuint shader;
shader=glCreateShader(GL_FRAGMENT_SHADER);
file=cast(char[])read(`program.frag`);
glShaderSource(f, 1, cast(char **) toStringz(file),null);
//let gc collect file
Error: Access Violation :)
I believe this should work:
char[] file;
file = toStringz(read("program.frag"));
glShaderSource(f, 1, &file, null);
What your program does, is treat the first chars of toStringz(file)
as a pointer, then wander off wildly in that direction.
A more D-like way of doing it would possibly be:
char[] file;
file = read("program.frag");
glShaderSource(f, 1, &file.ptr, &file.length);
