In Win32, size_t is defined as unsigned int, unsigned int and size_t are all 4 bytes long. In X64, unsigned int is a 32 bit type and size_t is a 64 bit type. If we pass a X64 int (4 bytes) as size_t (8 bytes) to a function which requires a 64bit size_t, we...
I mean, in a 64-bit system one can alloccate much more memory than 3GB, but what's the limit for a single array? In all the cases I am referring to dynamic allocation, using ALLOCATABLE arrays. Thanks! Kostas 翻译 标记: Intel® Fortran Compiler 0 项奖励 回复 ...

the low 32 bits of the register at the moment of call must represent a value between -32,768 and 32,767 (inclusive). Similar, if the caller passes anunsigned charargument in a register, the low 32 bits of the register at the moment of call must represent a value between 0 and 255 ...
