Re: Infinite Loop Question

I might be missing something here, but why are we not using the traditional:

while(1){... do stuff...}

This is what I use when I write deamons. Maybe it is bailing out due to lack of available memory?

`while (1)` and `for (;;)` (which is also quite traditional) result in the same code. $ perl -MO=Concise,-exec -e'for (;;) { f() }' 1 <0> enter 2 <;> nextstate(main 3 -e:1) v:{ 3 <{> enterloop(next->8 last->9 redo->4) v 4 <;> nextstate(main 1 -e:1) v 5 <0> pushmark s 6 <#> gv[f] s/EARLYCV 7 <1> entersub[t3] vKS/TARG,1 8 <0> unstack v -e syntax OK $ perl -MO=Concise,-exec -e'while (1) { f() }' 1 <0> enter 2 <;> nextstate(main 3 -e:1) v:{ 3 <{> enterloop(next->8 last->9 redo->4) v 4 <;> nextstate(main 1 -e:1) v 5 <0> pushmark s 6 <#> gv[f] s/EARLYCV 7 <1> entersub[t3] vKS/TARG,1 8 <0> unstack v -e syntax OK $ diff -u \ <( perl -MO=Concise,-exec -e'while (1) { f() }' 2>&1 ) \ <( perl -MO=Concise,-exec -e'for (;;) { f() }' 2>&1 ) \ && echo same same [download]	[reply] [d/l] [select]

No particular reason why I used `for(;;) {...}` instead of `while(1) {...}` It is my understanding that the two are pretty much interchangable.	[reply] [d/l] [select]
