Example:
-- snip --
#include <sfio.h>
#include <stk.h>
#include <stdio.h>
#include <stdlib.h>
static
const char *sfstrdup(Sfio_t *str, const char *s)
{
ssize_t pos=stktell(str);
sfputr(str, s, 0);
return stkptr(str, pos);
}
int main(int ac, char *av[])
{
Sfio_t *str= sfstropen();
const char *s;
printf("tell=%ld\n", (long)stktell(str));
s=sfstrdup(str, "hello");
printf("|%s|, tell=%ld\n", s, (long)stktell(str));
s=sfstrdup(str, "world");
printf("|%s|, tell=%ld\n", s, (long)stktell(str));
sfclose(str);
return EXIT_SUCCESS;
}
