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

      • childInSet

        public static int childInSet​(long attr,
                             long in,
                             long parent)
        Deprecated.
        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)
        Deprecated.
        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)
        Deprecated.
        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

        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:

      • cmdtypeSet

        public static int cmdtypeSet​(long attr,

 APR_PROGRAM_ENV  --  Executable program, copy environment
 APR_PROGRAM_PATH --  Executable program on PATH, copy env
        Returns:
        the operation status

        Returns:
        the operation status

      • errorCheckSet

        public static int errorCheckSet​(long attr,
                                int chk)
        Deprecated.
        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)
        Deprecated.
        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 yes.
        Returns:

      • errfnSet

        public static void errfnSet​(long attr,
                            long pool,
                            java.lang.Object o)
        Deprecated.
        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.

                          java.lang.String username,
