Depends what you mean by "safe". The spec says "don't use this"; it isn't any different to the __ and _[A-Z] prohibitions in that respect. Other posix namespace landgrabs you may not have expected: * ctype.h reserves "is[a-z]" and to[a-z]" prefixes * string.h takes "str[a-z]" and "mem[a-z]" prefixes (and qemu-common.h includes both string.h and ctype.h so this effectively applies to all of qemu). I'm in two minds about these, because on the one hand they're reserved but on the other hand abiding by the rules makes things uglier (whereas "use one underscore not two" doesn't produce an uglier name IMHO). (posix also if I'm reading it correctly reserves all of 'prefix underscore', which is annoying.) -- PMM
