Hello all. Today a question about sbrk(). I have this function to know free memory: long availmem(void) { static long initially=0; long limit; static long initial_limit; long burnt; if (!initially) { initially=_go32_dpmi_remaining_physical_memory(); assert(initially>0); } if (!initial_limit) initial_limit=(long)sbrk(0); limit=(long)sbrk(0); burnt=limit-initial_limit; return initially-burnt; } Well, I have got sbrk(0) to return negative values in some cases, so the function tells I have -1950Kb. Anybody has a solution? Thanks
