lpsantil / portable_endian.h

Last active August 29, 2015 14:27 — forked from panzi/portable_endian.h

This provides the endian conversion functions form endian.h on Windows, Linux, *BSD, and Mac OS X. You still need to use -std=gnu99 instead of -std=c99 for gcc. The functions might actually be macros. Functions: htobe16, htole16, be16toh, le16toh, htobe32, htole32, be32toh, le32toh, htobe64, htole64, be64toh, le64toh. License: I hereby put "port…

Things to commit just before leaving your job

	// Just before switching jobs:
	// Add one of these.
	// Preferably into the same commit where you do a large merge.
	//
	// This started as a tweet with a joke of "C++ pro-tip: #define private public",
	// and then it quickly escalated into more and more evil suggestions.
	// I've tried to capture interesting suggestions here.
