Methods Summary
public static native 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 param attr The procattr we care about. param addrspace Should the child start in its own address space? Default is no on NetWare and yes on other platforms.
public static native 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. param attr The procattr we care about. param err apr_file_t value to use as child_err. Must be a valid file. param parent apr_file_t value to use as parent_err. Must be a valid file.
public static native 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. param attr The procattr we care about. param in apr_file_t value to use as child_in. Must be a valid file. param parent apr_file_t value to use as parent_in. Must be a valid file.
public static native 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. param attr The procattr we care about. param out apr_file_t value to use as child_out. Must be a valid file. param parent apr_file_t value to use as parent_out. Must be a valid file.
public static native int	cmdtypeSet(long attr, int cmd) Set what type of command the child process will call. param attr The procattr we care about. param 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
public static native long	create(long cont) Create and initialize a new procattr variable param cont The pool to use return The newly created procattr.
public static native int	detachSet(long attr, int detach) Determine if the child should start in detached state. param attr The procattr we care about. param detach Should the child start in detached state? Default is no.
public static native int	dirSet(long attr, java.lang.String dir) Set which directory the child process should start executing in. param attr The procattr we care about. param 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.
public static native void	errfnSet(long attr, long pool, java.lang.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. param attr The procattr describing the child process to be created. param pool The the pool to use. param 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.
public static native 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. param attr The procattr describing the child process to be created. param 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.
public static native int	groupSet(long attr, java.lang.String groupname) Set the group used for running process param attr The procattr we care about. param groupname The group name used
public static native 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. param attr The procattr we care about. param in Should stdin be a pipe back to the parent? param out Should stdout be a pipe back to the parent? param err Should stderr be a pipe back to the parent?
public static native int	userSet(long attr, java.lang.String username, java.lang.String password) Set the username used for running process param attr The procattr we care about. param username The username used param password User password if needed. Password is needed on WIN32 or any other platform having APR_PROCATTR_USER_SET_REQUIRES_PASSWORD set.
