The mentioned test program, unfortunately sent to me.


#include <stdlib.h>
#include <stdio.h>
#include <printf.h>

int main()
{
int args[2], narg, size ;
char *format_pos_prec = "%10.2f",
     *format_neg_prec = "%10.-2f",
     *format_nul_prec = "10.0f",
     *format_dot_prec = "%10.f" ;
char buffer[32] ;

// print all four formats with the same argument

size = sprintf(buffer,format_pos_prec,2.51) ;
printf("format=%s ; size is %d ; result is \"%s\"\n",
    format_pos_prec,size,buffer) ;

size = sprintf(buffer,format_neg_prec,2.51) ;
printf("format=%s ; size is %d ; result is \"%s\"\n",
    format_neg_prec,size,buffer) ;

size = sprintf(buffer,format_nul_prec,2.51) ;
printf("format=%s ; size is %d ; result is \"%s\"\n",
    format_nul_prec,size,buffer) ;

size = sprintf(buffer,format_dot_prec,2.51) ;
printf("format=%s ; size is %d ; result is \"%s\"\n",
    format_dot_prec,size,buffer) ;

// try parse_print_format

narg = parse_printf_format(format_pos_prec,2,args) ;
printf("parse_printf_format() on %s : number of arguments is %d\n",
    format_pos_prec,narg) ;

narg = parse_printf_format(format_neg_prec,2,args) ;
printf("parse_printf_format() on %s : number of arguments is %d\n",
    format_neg_prec,narg) ;

narg = parse_printf_format(format_nul_prec,2,args) ;
printf("parse_printf_format() on %s : number of arguments is %d\n",
    format_nul_prec,narg) ;

narg = parse_printf_format(format_dot_prec,2,args) ;
printf("parse_printf_format() on %s : number of arguments is %d\n",
    format_dot_prec,narg) ;

exit(0) ;
}
