Method Summary

Modifier and TypeMethod and Description
public int

Returns:

Upon successful completion, the number of statfs structures is returned. Otherwise, -1 is returned and the global variable errno is set to indicate the error.
getfsstat64(SystemB.Statfs[]
Array of statfs structures that will be filled with results. If buf is given as NULL, getfsstat() returns just the number of mounted file systems.
buf, int
Size of the buffer to fill
bufsize, int
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 Some of the information returned may be out of date, however; if flags is set to MNT_WAIT or MNT_DWAIT instead, getfsstat() will request updated information from each mounted filesystem before returning.
flags)

The getfsstat() function returns information about all mounted file systems.

public SystemB.Group

Returns:

a Group structure matching that group
getgrgid(int
The group ID
gid)

This function searches the group database for the given group name pointed to by the group id given by gid, returning the first one encountered.

public int

Returns:

the process ID of the calling process.

Returns the process ID of the calling process.

public SystemB.Passwd

Returns:

a Passwd structure matching that user
getpwuid(int
The user ID
uid)

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

public int

Returns:

A 0 return value indicates that the call succeeded. A -1 return value indicates an error occurred, and in this case an error code is stored into the global variable errno.
gettimeofday(SystemB.Timeval
Timeval structure
tp, SystemB.Timezone
Timezone structure
tzp)

The system's notion of the current Greenwich time and the current time zone is obtained with the gettimeofday() call, and set with the settimeofday() call.

public int

Returns:

0 on success; sets errno on failure
host_page_size(int
The name (or control) port for the host for which the page size is desired.
hostPort, LongByReference
The host's page size (in bytes), set on success.

procInfo, IntByReference
Pointer to number of elements in the returned structure
procInfoCount)

The host_processor_info function returns information about processors.

public int

Returns:

0 on success; sets errno on failure
host_statistics(int
The control port for the host for which information is to be obtained.
hostPort, int
The type of statistics desired (HOST_LOAD_INFO, HOST_VM_INFO, or HOST_CPU_LOAD_INFO)
hostStat, Structure
Statistics about the specified host.
stats, IntByReference
On input, the maximum size of the buffer; on output, the size returned (in natural-sized units).
count)

The host_statistics function returns scheduling and virtual memory statistics concerning the host as specified by hostStat.

public int

Returns:

0 on success; sets errno on failure
host_statistics64(int
The control port for the host for which information is to be obtained.
hostPort, int
The type of statistics desired (HOST_VM_INFO64)
hostStat, Structure
Statistics about the specified host.
stats, IntByReference
On input, the maximum size of the buffer; on output, the size returned (in natural-sized units).
count)

The host_statistics64 function returns 64-bit virtual memory statistics concerning the host as specified by hostStat.

public int

Returns:

the host's name port
mach_host_self()

The mach_host_self system call returns the calling thread's host name port.

public int

Returns:

0 if successful, a kern_return_t code otherwise.
mach_port_deallocate(int
The port holding the right.
port, int
The port's name for the right.
name)

Decrement the target port right's user reference count.

public int

Returns:

the task's kernel port
mach_task_self()

The mach_task_self system call returns the calling thread's task_self port.
