[BusyBox] Clean up

[Tito]

Hi, 
one more funny solution:

/* in config.h */
#define CONFIG_FEATURE_CLEAN_UP

/* in busybox.h ? */
#ifdef CONFIG_FEATURE_CLEAN_UP

#include <stdio.h>    /* maybe not needed  */
#include <unistd.h>  /* maybe not needed  */
#include <stdlib.h>   /* maybe not needed  */

#define clean_up_free(x)            free(x)
#define clean_up_close(x)         close(x)
#define clean_up_fclose(x)        fclose(x)
/* something else needed here ? */

#else
#define clean_up_free(x)
#define clean_up_close(x)
#define clean_up_fclose(x)
#endif

/* test.c */
/*------------------------------------------------------------------*/
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdlib.h>


int main(int argc, char** argv) {
	
	int fd;
	char * ptr;
	
	ptr = malloc(4);
	fd = open("test_file", O_RDONLY);
	
	clean_up_close(fd);
	clean_up_free(ptr);
	
	exit(0);
}
/*---------------------------------------------------------------------*/


root at localhost:/dev/pts/2:/root# size test_with_cleanup
   text    data     bss     dec     hex filename
   1147     272       4    1423     58f test
root at localhost:/dev/pts/2:/root# size test_without_cleanup
   text    data     bss     dec     hex filename
   1012     264       4    1280     500 test

So this is very flexible, multiline friendly and almost understandable.....
for me at least ;-) 

Ciao,
Tito
