Implementations
Returns available resource names.
Returns available resources.
Returns the raw resource type.
Be careful: The actual type of RawResource
can be different on different platforms.
A limit (in seconds) on the amount of CPU time that the process can consume.
The maximum size (in bytes) of the process’s data segment (initialized data, uninitialized data, and heap).
(early Linux 2.4 only)
A limit on the combined number
of flock(2)
locks and fcntl(2)
leases
that this process may establish.
A limit on the number of bytes that can be allocated for POSIX message queues for the real user ID of the calling process.
This specifies a ceiling
to which the process’s nice value can be raised
using setpriority(2)
or nice(2)
.
This specifies a value one greater than the maximum file descriptor number that can be opened by this process.
A limit on the number of extant process (or, more precisely on Linux, threads) for the real user ID of the calling process.
A limit (in bytes) on the process’s resident set (the number of virtual pages resident in RAM).
This specifies a ceiling on the real-time priority
that may be set for this process
using sched_setscheduler(2)
and sched_setparam(2)
.
A limit (in microseconds) on the amount of CPU time that a process scheduled under a real-time scheduling policy may consume without making a blocking system call.
A limit on the number of signals that may be queued for the real user ID of the calling process.
