Re: va_arglist

Maybe this will help?

Although, I tried nesting some printf-like calls and had no success. 
Perhaps there's a trick to it?

#include <stdio.h>
#include <stdarg.h>

int testB(char *fmt, ...)
{
 va_list ap;

 va_start(ap, fmt);
 printf("%p  ", va_arg(ap, char *));
 printf("%c\n", va_arg(ap, int));
 va_end(ap);

 va_start(ap, fmt);
 vprintf(fmt, ap);
 va_end(ap);

 return(0);
}

int testA(char *fmt, ...)
{
 int rc = 0;
 va_list ap;

 va_start(ap, fmt);
 printf("%p  ", va_arg(ap, char *));
 printf("%c\n", va_arg(ap, int));
 va_end(ap);

 va_start(ap, fmt);
 rc = testB(fmt, ap);
 va_end(ap);

 return(rc);
}

int main(int argc, char *argv[])
{
 testA("Hello, %s%c\n", "World", '!');

 return(0);
}
