How do I use VirtualAlloc on the Linux platform?

[ebz]

Hello! I somewhat learned how to use VirtualAlloc on Windows, but not sure how to do the same thing on Linux.

I've got the following:

memory = (unsigned char*)VirtualAlloc(0, memorySize, MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);

I'd love to allocate a chunk of memory on linux as well :(

VirtualAlloc is Windows only.
If you use C then malloc, realloc and free are the normal choices.
If you use C++ you can use new and delete or even better use the STL containers and smart pointers.

Hey Thomas thanks for the quick reply. I'm actually doing a personal learning project and wanted to use an equivalent and avoiding smart pointers.

Is mmap a right choice in that case? I'm not sure how to use it,

Yes, this is the Linux equivalent function.

Read the manual, scroll down to the example.
