Judging by the docs, you don't need null-terminated strings and
can use native D strings, just pass their lengths:
string source = readText("test.glvert");
const char* sources = source.ptr;
const GLint len = cast(GLint)source.length;
GLuint vertShader = glCreateShader( GL_VERTEX_SHADER );
glShaderSource(vertShader, 1, &sources, &len);
Oh that also works quite well!
Is casting necessary there though? DerelictGL treats GL types as
D types, and .length is size_t so wouldn't it just turn into an
int regardless??
Also the one part I don't understand is with &sources. So is this
passing sources as a reference, but sources itself is a pointer
to a pointer? I'm just a tad confused on how this part works :S
