The file <gulliver.h> contains macros to help resolve endian issues.
The first thing you may need to know is the target system's endianness, which you can find out via the following macros:
A common coding style in the header files (e.g., <gulliver.h>) is to check which macro is defined and to report an error if none is defined:
#if defined(__LITTLEENDIAN__) // do whatever for little-endian #elif defined(__BIGENDIAN__) // do whatever for big-endian #else #error ENDIAN Not defined for system #endif
The #error statement will cause the compiler to generate an error and abort the compilation.
