hi all,
i was going through a tutorial on
implementing a threads library on linux. I have a
couple of doubts:
What i understand is the process address space
consists of
Stack
Unallocated space
Heap
Program code and data
Now my doubt is when i do a malloc
1) will memory be allocated from the heap ?
If yes, till what extent can it go pushing the heap
upwards ? What happens exactly ? some pointers wud be
helpfull with your comments .
2) When i do a malloc will the memory be allocated
physically from the heap - i.e would the newly
allocated memory be from the heap.I mean would the
addresses (of newly allocated memory by malloc()) be
the addresses of the memory locations of the heap ?
3) Process Adress spaces are fixed for all processes ?
If yes,What would happen if a process needs
comparitively large chunks of memmory which normal
programs won't need ?
thank you.
Amith
PS: i have more questions thought will post 2+1 at a
time :-)
