📖 Description

The verify_texture function takes a file path as input and attempts to open it in read-only mode to verify its existence.

• If the path pointer is NULL, the function immediately returns false.
• The function uses the open system call to try to open the file.
• If the file descriptor returned by open is negative, the file cannot be accessed, and the function returns false.
• If the file can be opened successfully, it closes the file descriptor and returns true.

💡 Example Usage

char *texture_path = "textures/north_wall.xpm";

if (verify_texture(texture_path)) {
    printf("Texture file exists and is accessible.\n");
} else {
    printf("Texture file does not exist or cannot be opened.\n");
}
