Functions

Entry function:

main() {
  expr;
}

Variables need to be declared first then assigned.

int getchar()

For stdin file: extern FILE *stdin;
int putchar(char)
int putc(char, FILE) / int fputc(char, FILE)

For stdout file: extern FILE *stdout;

There is also printer(?): extern File *stdprn
char *gets(char *) (unsafe)
 
char msg[8];
gets(msg);
pringf("Hello: %s",msg);
char fgets(char *, int buflen, FILE)
 
extern FILE *stdin;
main() {
  char msg[8];
  fgets(msg,8,stdin);
  pringf("Hello: %s",msg);
}
int puts(char *)
int fputs(char *,FILE)
printf(format, args, ...)
fpritf(FILE, format, args, ...)
sprintf(char *buf, format, args, ...)
int scanf(format, args, ...)
int fscanf(FILE, format, args, ...)
int sscanf(char *buf, format, args, ...)
int fflush(FILE)
int inport(int n)

outport(int n, int i)

clearerr(FILE in)

breakpt()

exit() / abort()

char *malloc(unsigned size)
char *calloc(unsigned n,unsigned size)
int free(char *)
