-
file_t
-
getcwdir (void);
-

-

-
Get file_t port name of current working directory. See <hurd/fs.defs> and <hurd/fs.h>.
-

-

-
int
-
setcwdir (file_t);
-
Set current working directory.
-

-

-
file_t
-
getcrdir (void);
-
Get file_t port name of current root directory.
-

-

-
int
-
setcrdir (file_t);
-

-

-
Set current root directory.
-

-

-
file_t
-
file_name_lookup (const char *file, int flags, mode_t mode);
-
Open a port to FILE with the given FLAGS and MODE (see <fcntl.h>). The file lookup uses the current root and working directory. Returns a port to the file if successful; otherwise sets errno and returns MACH_PORT_NULL.
-

-

-
file_t
-
file_name_lookup_under (file_t startdir, const char *file, int flags, mode_t mode);
-
Open a port to FILE with the given FLAGS and MODE (see <fcntl.h>). The file lookup uses the current root directory, but uses STARTDIR as the "working directory" for file relative names. Returns a port to the file if successful; otherwise sets errno and returns MACH_PORT_NULL.
-

-

-
file_t
-
file_name_path_lookup (const char *file_name, const char *path, int flags, mode_t mode, char **prefixed_name);
-
Lookup FILE_NAME and return the node opened with FLAGS & MODE (see hurd_file_name_lookup for details), but a simple file name (without any directory prefixes) will be consecutively prefixed with the pathnames in the : separated list PATH until one succeeds in a successful lookup. If none succeed, then the first error that wasn't ENOENT is returned, or ENOENT if no other errors were returned. If PREFIXED_NAME is non-NULL, then if the result is looked up directly, *PREFIXED_NAME is set to NULL, and if it is looked up using a prefix from PATH, *PREFIXED_NAME is set to malloc'd storage containing the prefixed name.
-

-

-
file_t
-
file_name_split (const char  file, char **name);
-
Split FILE into a directory and a name within the directory. The directory lookup uses the current root and working directory. If successful, stores in *NAME a pointer into FILE where the name within directory begins and returns a port to the directory; otherwise sets errno and returns MACH_PORT_NULL.
-

-

-
file_t
-
directory_name_split (const char *file, char **name);
-

-

-
Split DIRECTORY into a parent directory and a name within the directory. This is the same as file_name_split, but ignores trailing slashes.
-

-

-
FILE *
-
fopenport (io_t port, const char *mode);
-
Open a stream on a port. MODE is as for fopen. If successful, this consumes a user reference for PORT (which will be deallocated on fclose).
-

-

-
int
-
openport (io_t port, int flags);
-

-

-
Open a file descriptor on a port. FLAGS are as for open; flags affected by io_set_openmodes are not changed by this. If successful, this consumes a user reference for PORT (which will be deallocated on close.) See <hurd/io.defs> and <hurd/io.h>.
-

-

-
task_t
-
pid2task (pid_t pid);
-

-

-
Return the task control port of process PID. On error, sets errno and returns MACH_PORT_NULL.
-

-

-
pid_t
-
task2pid (task_t task);
-
Return the PID of the task whose control port is TASK. On error, sets errno and returns -1.
-

-

-
int
-
geteuids (int n, uid_t *uidset);
-
Get the effective UID set.
-

-

-
int
-
seteuids (int n, const uid_t *uidset);
-
Set the effective UID set.
-

-

-
auth_t
-
getauth (void);
-
Get port name of current authentication server. See <hurd/auth.defs> and <hurd/auth.h>.
-

-

-
int
-
setauth (auth_t);
-

-

-
Set current authentication server.
-

-

-
process_t
-
getproc (void);
-
Get port name of current process server. See <hurd/process.defs> and <hurd/process.h>.
-

-

-
int
-
setproc (process_t);
-

-

-
Set current process server.
-

-

-
mach_port_t
-
getcttyid (void);
-
Get the CTTY port.
-

-

-
int
-
setcttyid (mach_port_t);
-
Set the CTTY port.
-

-

-
kern_return_t
-
get_privileged_ports (host_priv_t *host_priv_ptr, device_t *device_master_ptr);
-
Fetch the host privileged port and device master port from the process server.
-

-

-
mode_t
-
getumask (void);
-
Get the current `umask' value without changing it (this glibc functions is available only under GNU Hurd.)
-

-

-
int
-
vpprintf (io_t port, const char *format, va_list arg);
-
Write formatted output to PORT, a Mach port supporting the i/o protocol, according to the format string FORMAT, using the argument list in ARG.
-

-

-
thread_t
-
hurd_thread_self (void);
-
Return the current thread's thread port. This is a cheap operation (no system call), but it relies on Hurd signal state being set up.
-

-

-
error_t
-
hurd_thread_cancel (thread_t thread);
-

-

-
Cancel pending operations on THREAD. If it is doing an interruptible RPC, that RPC will now return EINTR; otherwise, the "cancelled" flag will be set, causing the next hurd_check_cancel call to return nonzero or the next interruptible RPC to return EINTR (whichever is called first).
-

-

-
int
-
hurd_check_cancel (void);
-

-

-
Test and clear the calling thread's "cancelled" flag.
