Does anyone know of a method of determining how much memory you have
left after a series of calls to malloc in 3L's Parallel C ?

How about use undocumented global variable "IMP___HEAP_LIMIT". It points top of heap. So you can estimate free memory left by subtracting this value from current stack address like following. int free_mem() { extern char *IMP___HEAP_LIMIT; char tmp; return &tmp - IMP___HEAP_LIMIT; } -- $@@nJUK~FA!w!J3t!K0B@nEE5!@=:n=j(J $@8&5f=j(J $@8&5fBh#1%0%k!<%W(J TEL (093)641-3111 FAX (093)631-8440 kawa@yesun.yelab.yaskawa.co.jp
