 Events/Actions
 --------------
 (1) Register with finder.
 (2) External dependencies satisfied, ready to be configured.
 (3) Finished processing any config changes, ready for other
     processes that depend on this process to be configured.
 (4) Received a config change that needs to be processed before other
     processes that depend on this process are configured.
 (5) Received a request for a clean shutdown.
 (6) Something failed, this process is no longer functioning correctly.
 (7) The shutdown has completed.
 (8) The process has completed the cleanup after the failure.
 (9) Deregister with finder.

 States
 ------
 PROC_NULL        Process is not registered with finder.  It may or may
                  not be running.

 PROC_STARTUP     Process is registered with finder, but is waiting
                  on some other processes before it is ready to be
                  configured.

 PROC_NOT_READY   For any reason, the process is not ready for processes
                  that depend on this process to be configured or
                  reconfigured.  A common reason is that this
                  process just received a config change, and is
                  still in the process of making the config change
                  active.

 PROC_READY       Process is running normally.  Processes that depend
                  on the state of this process can be configured or
                  reconfigured.

 PROC_SHUTDOWN    Process has received a shutdown request is shutting
                  down cleanly.  Normally the process will terminate by
                  itself after being in this state.

 PROC_FAILED      Process has suffered a fatal error, and is in the
                  process of cleaning up the mess.  Normally the process
                  will terminate by itself after being in this state.

 PROC_DONE        The process has completed operation, but is still
                  capable of responding to XRLs.

 Notes
 -----

 A process may spend zero time in PROC_STARTUP, PROC_NOT_READY,
 PROC_READY, PROC_SHUTDOWN, PROC_FAILED, or PROC_DONE states.  For
 example, a process may effectively go directly from PROC_NULL to
 PROC_READY state on startup if there are no dependencies that need
 to be taken into account.  A process may go from PROC_STARTUP or
 PROC_NOT_READY states to PROC_SHUTDOWN or PROC_FAILED states
 without spending any time in PROC_READY state if required.

 On reconfiguration, a process does not need to go to NOT_READY
 state unless it needs to delay the reconfiguration of processes
 that depend on the completion of this reconfiguration.

 After shutdown or a failure, the process may remain indefinitely in
 PROC_DONE state (e.g., if the process itself shoudn't really exit
 but rather await further instructions).

FILE*  xorp_make_temporary_file (const string& tmp_dir, const string& filename_template, string& final_filename, string& errmsg)

xorp_make_temporary_file

#include <utils.hh>


Create a temporary file with unique name.

This function takes the given file name template, and adds a suffix to it to create an unique file name in a chosen temporary directory. The temporary directory is selected from the following list by choosing the first directory that allows us the create the temporary file (in the given order): (a) The value of one of the following environment variables if defined (in the given order): - "TMPDIR" - "TEMP" (Windows only) - "TMP" (Windows only) (b) Argument tmp_dir if it is not an empty string. (c) The system-specific path of the directory designated for temporary files: - GetTempPath() (Windows only) (d) The "P_tmpdir" directory if this macro is defined (typically in the <stdio.h> include file). (e) The first directory from the following list we can write to: - "C:\TEMP" (Windows only) - "/tmp" (UNIX only) - "/usr/tmp" (UNIX only) - "/var/tmp" (UNIX only)

For example, if the file name template is "foo", and if the chosen temporary directory is "/tmp", then the temporary file name would be like "/tmp/foo.XXXXXX" where "XXXXXX" is alpha-numerical suffix chosen automatically to compose the unique file name. The created file has mode 0600 (i.e., readable and writable only by the owner).

Parameters:

tmp_dirthe preferred directory to store the file.
filename_templatethe file name template.
final_filenamea return-by-reference argument that on success returns the final name of the temporary file (including the directory name).
errmsgthe error message (if error).

Returns: a file descriptor pointer for the temporary file (opened for reading and writing) on success, otherwise NULL.

void  win_quote_args (const list<string>& args, string& cmdline)

win_quote_args

#include <utils.hh>


Helper function to quote command line arguments for MSVCRT-linked programs.

Given an argv array represented by an STL list of strings, and a writable command line string, walk through the arguments and perform quoting/escaping according to the rules for invoking programs linked against the Microsoft Visual C Runtime Library.

This function is necessary because the Win32 CreateProcess() API function accepts a single command line string, as opposed to a UNIX-style argv[] array; arguments must therefore be delimited by white space, so white space in arguments themselves must be quoted.

Note that such extensive quoting shouldn't be performed for the pathname to the executable -- generally it is desirable to only wrap the path name with quotes, and then pass that string to this helper function.

Parameters:

argslist of argument strings to be escaped.
cmdlinestring to which the escaped command line should be appended.
