[9fans] srprint...

[steve-simon]

Hi,

I copied and modified the standard libraries smprint()
producing a mutant srprint(Fmt *f, char *fmt, ...);

The idea is that you can call it with a zero'ed Fmt pointer
and then keep srprint()ing into an growing buffer.

I have a filesystem which generates largeish virtual files
(<= 10 Kbytes) which is generated when the file is opened,
This seemed to be the best way to do it but I cannot beleive
noone has had this problem before.

The srprint() returns a pointer to the buffer like smprint()
for disposition and eventual free()ing.

If there is a cleaner way to do this I would like to know.
If people think its nice I could submit it.

Not sure if I'am proud or ashamed...

you can use fmtprint(2) to do this, if i understand your problem correctly.
