This function searches the password database for the given user uid,
always returning the first one encountered.
|
int |

The mach_host_self system call returns the calling thread's host name
port.
|
int |
mach_task_self()
The mach_task_self system call returns the calling thread's task_self
port.
|
int |
proc_listpids(int type,
int typeinfo,
int[] buffer,
int buffersize)
Search through the current processes

int |
proc_pid_rusage(int pid,
int flavor,
SystemB.RUsageInfoV2 buffer)
Return resource usage information for the given pid, which can be a live
process or a zombie.
|
int |
proc_pidinfo(int pid,
int flavor,
long arg,
Structure buffer,
int buffersize)
Return in buffer a proc_*info structure corresponding to the flavor for
the specified process
|
int |
proc_pidpath(int pid,
Pointer buffer,
int buffersize)
Return in buffer the name of the specified process
|
int |
sysctl(int[] name,
int namelen,
Pointer oldp,
IntByReference oldlenp,
Pointer newp,
int newlen)
The sysctl() function retrieves system information and allows processes
with appropriate privileges to set system information.
|
int |
sysctlbyname(java.lang.String name,
Pointer oldp,
IntByReference oldlenp,
Pointer newp,
int newlen)
The sysctlbyname() function accepts an ASCII representation of the name
and internally looks up the integer name vector.
|
int |
sysctlnametomib(java.lang.String name,
Pointer mibp,
IntByReference size)
The sysctlnametomib() function accepts an ASCII representation of the
name, looks up the integer name vector, and returns the numeric
representation in the mib array pointed to by mibp.

- If flags is set to MNT_NOWAIT, getfsstat() will directly
return the information retained in the kernel to avoid delays
caused by waiting for updated information from a file system
that is perhaps temporarily unable to respond. Some of the
information returned may be out of date, however; if flags is
set to MNT_WAIT or MNT_DWAIT instead, getfsstat() will request
updated information from each mounted filesystem before
returning.int getpid()
