On GNU libc systems, print a crude backtrace to stderr. On other systems, print "no backtrace support" and block for possible gdb attachment if an appropriate environment variable is set. Definition at line 2211 of file dbus-sysdeps-unix.c. Referenced by _dbus_abort(). |

Reads a single byte which must be nul (an error occurs otherwise), and reads unix credentials if available. Fills in pid/uid/gid with -1 if no credentials are available. Return value indicates whether a byte was read, not whether we got valid credentials. On some systems, such as Linux, reading/writing the byte isn't actually required, but we do it anyway just to avoid multiple codepaths. Fails if no byte is available, so you must select() first. The point of the byte is that on some systems we have to use sendmsg()/recvmsg() to transmit credentials.

Reads the uuid of the machine we're running on from the dbus configuration. Optionally try to create it (only root can do this usually). On UNIX, reads a file that gets created by dbus-uuidgen in a post-install script. On Windows, if there's a standard machine uuid we could just use that, but I can't find one with the right properties (the hardware profile guid can change without rebooting I believe). If there's no standard one we might want to use the registry instead of a file for this, and I'm not sure how we'd ensure the uuid gets created.

Sends a single nul byte with our UNIX credentials as ancillary data. Returns TRUE if the data was successfully written. On systems that don't support sending credentials, just writes a byte, doesn't send any credentials. On some systems, such as Linux, reading/writing the byte isn't actually required, but we do it anyway just to avoid multiple codepaths. Fails if no byte can be written, so you must select() first. The point of the byte is that on some systems we have to use sendmsg()/recvmsg() to transmit credentials.

Wrapper for setenv(). If the value is NULL, unsets the environment variable. There is an unfixable memleak in that it is unsafe to free memory malloced for use with setenv. This is because we can not rely on internal implementation details of the underlying libc library.
