Macro Definition Documentation

XXH_CPU_LITTLE_ENDIAN

#define XXH_CPU_LITTLE_ENDIAN   XXH_isLittleEndian()

Whether the target is little endian.

Defined to 1 if the target is little endian, or 0 if it is big endian. It can be defined externally, for example on the compiler command line.

If it is not defined, a runtime check (which is usually constant folded) is used instead.

Note

This is not necessarily defined to an integer constant.

See also

XXH_isLittleEndian() for the runtime check.

XXH_DEBUGLEVEL

#define XXH_DEBUGLEVEL   DEBUGLEVEL

Sets the debugging level.

XXH_DEBUGLEVEL is expected to be defined externally, typically via the compiler's command line options. The value must be a number.
