• Procattr

  public Procattr()

Method Detail

• create

  public static long create(long cont)
                     throws Error

  Create and initialize a new procattr variable

  Parameters:

  cont - The pool to use

  Returns:

  The newly created procattr.

  Throws:

  Error - An error occurred

• ioSet

  public static int ioSet(long attr,
          int in,
          int out,
          int err)

  Determine if any of stdin, stdout, or stderr should be linked to pipes when starting a child process.

  Parameters:

  attr - The procattr we care about.

  in - Should stdin be a pipe back to the parent?

  out - Should stdout be a pipe back to the parent?

  err - Should stderr be a pipe back to the parent?

  Returns:

  the operation status

• childInSet

  public static int childInSet(long attr,
               long in,
               long parent)

  Set the child_in and/or parent_in values to existing apr_file_t values.
  This is NOT a required initializer function. This is useful if you have already opened a pipe (or multiple files) that you wish to use, perhaps persistently across multiple process invocations - such as a log file. You can save some extra function calls by not creating your own pipe since this creates one in the process space for you.

  Parameters:

  attr - The procattr we care about.

  in - apr_file_t value to use as child_in. Must be a valid file.

  parent - apr_file_t value to use as parent_in. Must be a valid file.

  Returns:

  the operation status

• childOutSet

  public static int childOutSet(long attr,
                long out,
                long parent)

  Set the child_out and parent_out values to existing apr_file_t values.
  This is NOT a required initializer function. This is useful if you have already opened a pipe (or multiple files) that you wish to use, perhaps persistently across multiple process invocations - such as a log file.

  Parameters:

  attr - The procattr we care about.

  out - apr_file_t value to use as child_out. Must be a valid file.

  parent - apr_file_t value to use as parent_out. Must be a valid file.

  Returns:

  the operation status

• childErrSet

  public static int childErrSet(long attr,
                long err,
                long parent)

  Set the child_err and parent_err values to existing apr_file_t values.
  This is NOT a required initializer function. This is useful if you have already opened a pipe (or multiple files) that you wish to use, perhaps persistently across multiple process invocations - such as a log file.

  Parameters:

  attr - The procattr we care about.

  err - apr_file_t value to use as child_err. Must be a valid file.

  parent - apr_file_t value to use as parent_err. Must be a valid file.

  Returns:

  the operation status

• dirSet

  public static int dirSet(long attr,
           String dir)

  Set which directory the child process should start executing in.

  Parameters:

  attr - The procattr we care about.

  dir - Which dir to start in. By default, this is the same dir as the parent currently resides in, when the createprocess call is made.

  Returns:

  the operation status

• cmdtypeSet

  public static int cmdtypeSet(long attr,
               int cmd)

  Set what type of command the child process will call.

  Parameters:

  attr - The procattr we care about.

  cmd - The type of command. One of:

   APR_SHELLCMD     --  Anything that the shell can handle
   APR_PROGRAM      --  Executable program   (default)
   APR_PROGRAM_ENV  --  Executable program, copy environment
   APR_PROGRAM_PATH --  Executable program on PATH, copy env
   

  Returns:

  the operation status

• detachSet

  public static int detachSet(long attr,
              int detach)

  Determine if the child should start in detached state.

  Parameters:

  attr - The procattr we care about.

  detach - Should the child start in detached state? Default is no.

  Returns:

  the operation status

• errorCheckSet

  public static int errorCheckSet(long attr,
                  int chk)

  Specify that apr_proc_create() should do whatever it can to report failures to the caller of apr_proc_create(), rather than find out in the child.

  Parameters:

  attr - The procattr describing the child process to be created.

  chk - Flag to indicate whether or not extra work should be done to try to report failures to the caller.
  This flag only affects apr_proc_create() on platforms where fork() is used. This leads to extra overhead in the calling process, but that may help the application handle such errors more gracefully.

  Returns:

  the operation status

• addrspaceSet

  public static int addrspaceSet(long attr,
                 int addrspace)

  Determine if the child should start in its own address space or using the current one from its parent

  Parameters:

  attr - The procattr we care about.

  addrspace - Should the child start in its own address space? Default is no on NetWare and yes on other platforms.

  Returns:

  the operation status

• errfnSet

  public static void errfnSet(long attr,
              long pool,
              Object o)

  Specify an error function to be called in the child process if APR encounters an error in the child prior to running the specified program.

  Parameters:

  attr - The procattr describing the child process to be created.

  pool - The the pool to use.

  o - The Object to call in the child process.
  At the present time, it will only be called from apr_proc_create() on platforms where fork() is used. It will never be called on other platforms, on those platforms apr_proc_create() will return the error in the parent process rather than invoke the callback in the now-forked child process.

• userSet

  public static int userSet(long attr,
            String username,
            String password)

  Set the username used for running process

  Parameters:

  attr - The procattr we care about.

  username - The username used

  password - User password if needed. Password is needed on WIN32 or any other platform having APR_PROCATTR_USER_SET_REQUIRES_PASSWORD set.

  Returns:

  the operation status

• groupSet

  public static int groupSet(long attr,
             String groupname)

  Set the group used for running process

  Parameters:

  attr - The procattr we care about.

  groupname - The group name used

  Returns:

  the operation status
