I know it's not strictly C, but it IS the secondary group...
The new console functions in version 1.5 of turbo c are really swell
and everything, (swollen too, if you check the size of the executable)
but they aren't much good if you want to write on the graphics screen.
Your only choice is `outtext{xy}', whose argument must be a string.
Has anybody got any great ideas about how to formatted text output
on the graphics screen, i.e., `gprintf(format, arg, ..., arg)' ???
Is this dopey? Am I a buffoon? Do I have to do it myself for goodness sake?
oomingmak and all that,
rob

Try sprintf() to format the string and then use your string output function.

How about this (appologies for source in this newsgroup... It's short) #include <stdio.h> #include <stdarg.h> void gprintf(int x, int y, char *fmt, ...) { va_list params; char str[80]; va_start(params,fmt); vsprintf(str,fmt,params); va_end(params); outtextxy(x,y,(char far *) str); } I may have left off a graphics library header here. This is untested. Don't forget to prototype it where used. void gprintf(int x, int y, char *fmt, ...); usage: gprintf(1, 1, "Hi mom, i=%d", i); No warranties, I speak only for myself, ...

Note that this limits you to printing 80 characters or less. If you had a function-style stdio, you could do this: #include <stdio.h> #include <stdarg.h> /* etc */ #define GP_BUFSIZE 80 /* or whatever */ static int gwrite(void *context, const char *buf, int n) { char *realbuf = (char *)context; int k, left = n; while (left > 0) { k = left > GP_BUFSIZE ? GP_BUFSIZE : left; (void) memmove((void *)realbuf, (void *)buf, k); realbuf[k] = 0; outtext(realbuf); buf += k; left -= k; } return (n); } int gprintf(char *fmt, ...) { FILE *fp; va_list ap; int rv; char buf[GP_BUFSIZE + 1]; /* leave room for '\0'! */ if ((fp = fwopen((void *)buf, gwrite)) == NULL) return (-1); va_start(ap, fmt); rv = vfprintf(fp, fmt, ap); va_end(ap); (void) fclose(fp); return (rv); } A bit clumsy, I admit, but this has no output restrictions. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7163) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris
