How about an saprintf?

size_t saprintf(char *buf, const char *formatstr, void **args);
size_t sanprintf(char *buf, size_t size, const char *formatstr, void **args=
);

Put simply, it works like sprintf, but takes arguments in a void * array.=20
Arguments which are not pointers must be stored and passed as a pointer to=
=20
said storage. Or would this go in another module?

Example:
char buf[1024];
char str1[1024] =3D "The number is: ";
char str2[1024] =3D "!";

int x =3D 42;
void *args[3];
args[0] =3D str1;
args[1] =3D &x;
args[2] =3D str2;

sanprintf(buf, 1024, "%s%d%s\n", args);

This would be useful if the format string is built at runtime - e.g. for an=
=20
interpreter for some other language.
