scf2read(3) Staden Package scf2read(3) NAME
scf2read, read2scf, exp2read, read2exp - Translate to and from the Read structure. SYNOPSIS
#include <Read.h> Read *scf2read( Scf *scf); Scf *read2scf( Read *read); Exp_info *read2exp( Read *read, char *EN); Read *exp2read( Exp_info *e); DESCRIPTION
These functions are used internally by the io library for converting between the in memory representations of the supported file formats. The Read structure is the central format so only conversion to and from this structure is available. Conversions consist of to and from the SCF format and to and from the Experiment File format. scf2read() converts an Scf structure into a Read structure. The Read structure is allocated by the function. The Scf structure is left unchanged. read2scf() converts a Read structure into an Scf structure. The Scf structure is allocated by the function. The Read structure is left unchanged. exp2read() converts an Exp_info structure into a Read structure. The entryname to use in the EN line type of the Experiment File must be specified. The Read structure is allocated by the function. The Exp_info structure is left unchanged. read2exp() converts a Read structure into an Exp_info structure. The Exp_info structure is allocated by the function. The Read structure is left unchanged. RETURN VALUES
On successful completion, the scf2read() and exp2read functions return a pointer to an allocated Read structure. Otherwise these functions return NULLRead. On successful completion, the read2scf function returns a pointer to an allocated Scf structure. Otherwise this function returns a null pointer. On successful completion, the read2exp function returns a pointer to an allocated Exp_info structure. Otherwise this function returns a null pointer. SEE ALSO

SDL_Surface- Graphical Surface Structure STRUCTURE DEFINITION
typedef struct SDL_Surface { Uint32 flags; /* Read-only */ SDL_PixelFormat *format; /* Read-only */ int w, h; /* Read-only */ Uint16 pitch; /* Read-only */ void *pixels; /* Read-write */ /* clipping information */ SDL_Rect clip_rect; /* Read-only */ /* Reference count -- used when freeing surface */ int refcount; /* Read-mostly */ /* This structure also contains private fields not shown here */ } SDL_Surface; STRUCTURE DATA
flags Surface flags format Pixel format w, h Width and height of the surface pitch Length of a surface scanline in bytes pixels Pointer to the actual pixel data clip_rect surface clip rectangle DESCRIPTION
SDL_Surface's represent areas of "graphical" memory, memory that can be drawn to. The video framebuffer is returned as a SDL_Surface by SDL_SetVideoMode and SDL_GetVideoSurface. Most of the fields should be pretty obvious. w and h are the width and height of the surface in pixels. pixels is a pointer to the actual pixel data, the surface should be locked before accessing this field. The clip_rect field is the clipping rectangle as set by SDL_SetClipRect. The following are supported in the flags field. SDL_SWSURFACE Surface is stored in system memory SDL_HWSURFACE Surface is stored in video memory SDL_ASYNCBLIT Surface uses asynchronous blits if possible SDL_ANYFORMAT Allows any pixel-format (Display surface) SDL_HWPALETTE Surface has exclusive palette SDL_DOUBLEBUF Surface is double buffered (Display surface) SDL_FULLSCREEN Surface is full screen (Display Surface) SDL_OPENGL Surface has an OpenGL context (Display Surface) SDL_OPENGLBLIT Surface supports OpenGL blitting (Display Surface) SDL_RESIZABLE Surface is resizable (Display Surface) SDL_HWACCEL Surface blit uses hardware acceleration SDL_SRCCOLORKEY Surface use colorkey blitting SDL_RLEACCEL Colorkey blitting is accelerated with RLE SDL_SRCALPHA Surface blit uses alpha blending SDL_PREALLOC Surface uses preallocated memory SEE ALSO
