Or just use auto of course if you prefer:
void load (string path)
{
import std.string : toStringz;
auto ab = SDL_LoadBMP (path.toStringz);

try the following:
```
void load (string path)
{
import std.string : toStringz;
SDL_Surface ab = SDL_LoadBMP (path.toStringz); // toStringz
converts string to null terminated char*
auto a = SDL_CreateTextureFromSurface (ab);
SDL_FreeSurface (ab);
}
Also, the return type of SDL_LoadBMP is a pointer, SDL_Surface*
not just SDL_Surface.
Indeed, in your code do use the D string path, not char*, and use
toStringz when passing to C APIs.
Also, in D const(char)* would not be the same as const(char*).
But don't worry about this and use string.

The problem with the conversion.
Hello, users of this programming language! I have a question. I
use in my application Derelict SDL 2 version 2.1.4.
And when I try to specify the path to the image:
void load (const (char *) path)
{
SDL_Surface ab = SDL_LoadBMP (path);
a = SDL_CreateTextureFromSurface (ab);
SDL_FreeSurface (ab);
}
An error occurs:
"function derelict.sdl2.functions.SDL_LoadBMP (const (char) *
file) is not callable using argument types (string)".
Well, okay, I use in arguments: const (char *) path. Annoyed, the
program still writes this error. Please help with this problem.
P.S. If you see errors in spelling and stuff, then note: I am a
Russian user.
P.P.S. I am not familiar with this programming language.
