Subject: [PATCH] src/pipe.c: fix build error with gcc 7.x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The write function takes a char* as argument, not a char.

Fixes:

pipe.cpp: In member function ‘void DBus::Pipe::signal()’:
pipe.cpp:86:29: error: invalid conversion from ‘char’ to ‘const void*’ [-fpermissive]
   ::write(_fd_write, '\0', 1);
                             ^
