we have developed win32 application x86 , x64 platform. want use same application on arm platform. endianness vary arm platform i.e. arm platform uses big endian format in general. want handle in our application our device. for e.g. // in x86/x64, int nintval = 0x12345678 in arm, int nintval = 0x78563412 how values stored following data types in arm? double char array i.e. char chbuffer[256] int64 please clarify this. regards, raphel endianess matters register <-> memory operations. in register there no endianess. if put int nintval = 0x12345678 in code have same effect on endianess machine. all ieee formats ( float , double ) identical in architectures, not matter. you have care endianess in 2 cases: a) write integers files have transferable between 2 architectures. solution: use hton*, ntoh* family of converters, use non-binary file format (e.g. xml) or standardised file format (e.g. sqlite). b) cast integer pointers. int = 0x18758...
