Subject: how many function calls deep am I?
Message-ID: <F503444EAC@fs2.mt.umist.ac.uk>

int depth(){long j,i;for(i=long(&i+2),j=0;i;i=*((long*)i),j++);return j;}

I wrote this short function. In djgpp (at least in version 1) it gives how
many stack call levels deep you are, so that e.g. you can easily indent trace
output with depth() number of spaces or `#''s at the start of each line, to
keep track of function entries and exits somewhat.
