MakeErrMsg()

static bool MakeErrMsg ( std::string *  ErrMsg, const std::string &  prefix, int  errnum = -1  )

inlinestatic

This function builds an error message into ErrMsg using the prefix string and the Unix error number given by errnum.

If errnum is -1, the default then the value of errno is used. Make an error message

If the error number can be converted to a string, it will be separated from prefix by ": ".
