In a large system I try to allocate about 1GB of memory on a 4GB
system and it blows up (returns a NULL pointer in C), Now I tried to
allocate 1GB from a small test program and it also returns null.
Also, I have implemented the /LARGEADDRESSLIMIT switch on the Linker,
to be able to address more than 2GB RAM. But the system does not want
to allocate 1GB, when the available memory is 1.8GB according to the
ex: BYTE *bb=(BYTE*) calloc(0.9, 0x40000000);
where BYTE is unsigned char
I can only allocate about 400MB, otherwise I get NULL
How much memory I can allocate from a C program ?
It looks like there is something I don't quite understand about the x86
