getpid() returns the process ID of the calling process. The ID is guaranteed to be unique and is useful for constructing temporary file names. getppid() returns the process ID of the parent of the cal...
The scheduling priority of the process, process group, or user, as indicated by which and who is obtained with the getpriority() call and set with the setpriority() call. which is one of PRIO_PROCESS,...
Limits on the consumption of system resources by the current process and each process it creates may be obtained with the getrlimit() call, and set with the setrlimit() call. Resources of an arbitrary...
getrusage() returns information describing the resources utilized by the current process, or all its terminated child processes. The who parameter is either RUSAGE_SELF or RUSAGE_CHILDREN. The buffer ...
The getsid function returns the session ID of the process specified by pid. If pid is 0, the session ID of the calling process is returned. The session ID is defined as the process group ID of the pro...
The getsockname() system call returns the current name for the specified socket. The namelen parameter should be initialized to indicate the amount of space pointed to by name. On return it contains t...
getsockopt() and setsockopt() manipulate the options associated with a socket. Options may exist at multiple protocol levels; they are always present at the uppermost ``socket'' level. When manipula...
Note: time zone information is no longer provided by this interface. See localtime(3) for information on how to retrieve it. The system's notion of the current UTC time is obtained with the gettimeof...
The getuid() function returns the real user ID of the calling process. The geteuid() function returns the effective user ID of the calling process. The real user ID is that of the user who has invoked...
i386_get_ioperm() copies the current I/O permission bitmap into the memory referenced by iomap. i386_set_ioperm() sets the I/O permission bitmap from the data pointed to by iomap. This call is restric...
i386_get_ldt() will return the list of i386 descriptors that the process has in its LDT. i386_set_ldt() will set a list of i386 descriptors for the current process in its LDT. Both routines accept a s...
These functions provide an interface to the MTRR registers found on 686-class processors for controlling processor access to memory ranges. This is most useful for accessing devices such as video acce...
These functions provide an interface to the CPU performance counters on the 586-class and 686-class processors. i386_pmc_info() will return information about the available CPU counters. The informatio...
