[voorugonda prashanth]

hi all, how much heap memory allocated for a process? how much stack memory allocated for a process? if i have 512MB RAM and trying allocate 1GB of Heap memory what will happen?? please explain or give me links. Thanks in advance.

Default heap size is 1mb,this can be changed using the /heap linker option.An application can directly use about 2gb of address space. Same for stack also,1mb is the default and can be changed using the /stack linker option

It will attempt to allocate the memory from virtual memory

BTW, 2GB is for 32-bit Windows, which is the total limit of stack plus heap plus none-user memory. Best, Jun
