Question

What does the inline keyword do in C?

for example:
inline void centerText(const char *, short int);
inline void drawBorder(void);
void drawLogo(void);
void drawSelector(short int);
inline void drawCopyright(void);
void drawMenu(void);
void drawSpeedOption(short int);
void drawDifficultyOption(short int);
inline void drawOptionsMenu(short int, short int);
inline void drawBlock(short int, short int, unsigned char *, short int);
inline void drawToken(short int, short int, unsigned char *);
inline void drawScore(unsigned long int);

Answer 1

btw these are just function prototypes

Answer 2

inline void drawBlock(short int x, short int y, unsigned char *sprite, short int mode) {
Sprite8(x,y,HEIGHT,sprite,LCD_MEM,mode);
}
