SDL_FreeSurface(3) SDL API Reference SDL_FreeSurface(3)NAME
SDL_FreeSurface- Frees (deletes) a SDL_Surface
SYNOPSIS
#include "SDL.h"
void SDL_FreeSurface(SDL_Surface *surface);
DESCRIPTION
Frees the resources used by a previously created SDL_Surface. If the surface was created using SDL_CreateRGBSurfaceFrom then the pixel data
is not freed.

SDL_CreateRGBSurface - Create an empty SDL_Surface
SYNOPSIS
#include "SDL.h"
SDL_Surface *SDL_CreateRGBSurface(Uint32 flags, int width, int height, int depth, Uint32 Rmask, Uint32 Gmask, Uint32 Bmask, Uint32 Amask);
DESCRIPTION
Allocate an empty surface (must be called after SDL_SetVideoMode)
If depth is 8 bits an empty palette is allocated for the surface, otherwise a 'packed-pixel' SDL_PixelFormat is created using the
[RGBA]mask's provided (see SDL_PixelFormat). The flags specifies the type of surface that should be created, it is an OR'd combination of
the following possible values.
SDL_SWSURFACE SDL will create the surface in system memory. This improves the performance of pixel level access, however you may not
be able to take advantage of some types of hardware blitting.
SDL_HWSURFACE SDL will attempt to create the surface in video memory. This will allow SDL to take advantage of Video->Video blits
(which are often accelerated).
SDL_SRCCOLORKEY This flag turns on colourkeying for blits from this surface. If SDL_HWSURFACE is also specified and colourkeyed blits
are hardware-accelerated, then SDL will attempt to place the surface in video memory. Use SDL_SetColorKey to set or
clear this flag after surface creation.
SDL_SRCALPHA This flag turns on alpha-blending for blits from this surface. If SDL_HWSURFACE is also specified and alpha-blending
blits are hardware-accelerated, then the surface will be placed in video memory if possible. Use SDL_SetAlpha to set or
clear this flag after surface creation.
Note:
If an alpha-channel is specified (that is, if Amask is nonzero), then the SDL_SRCALPHA flag is automatically set. You may remove
this flag by calling SDL_SetAlpha after surface creation.
RETURN VALUE
Returns the created surface, or NULL upon error.
EXAMPLE
/* Create a 32-bit surface with the bytes of each pixel in R,G,B,A order,
as expected by OpenGL for textures */
SDL_Surface *surface;
Uint32 rmask, gmask, bmask, amask;
/* SDL interprets each pixel as a 32-bit number, so our masks must depend
on the endianness (byte order) of the machine */
#if SDL_BYTEORDER == SDL_BIG_ENDIAN
rmask = 0xff000000;
gmask = 0x00ff0000;
bmask = 0x0000ff00;
amask = 0x000000ff;
#else
rmask = 0x000000ff;
gmask = 0x0000ff00;
bmask = 0x00ff0000;
amask = 0xff000000;
#endif
surface = SDL_CreateRGBSurface(SDL_SWSURFACE, width, height, 32,
rmask, gmask, bmask, amask);
if(surface == NULL) {
fprintf(stderr, "CreateRGBSurface failed: %s
", SDL_GetError());
exit(1);
}

Hi,
What is installation package and how to create it?
When we run:
in AIX:
installp package1
or
in Linux
rpm -ivh mypackage
What is package1 or mypackage in the abov examples and how to create them and deploy them?
I hope my question is clear enough.
Thank you (2 Replies)
What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
