array posix_getrlimit ( void )

posix_getrlimit() returns an array of information about the current resource's soft and hard limits.

Each resource has an associated soft and hard limit. The soft limit is the value that the kernel enforces for the corresponding resource. The hard limit acts as a ceiling for the soft limit. An unprivileged process may only set its soft limit to a value from 0 to the hard limit, and irreversibly lower its hard limit.

Возвращаемые значения

Returns an associative array of elements for each limit that is defined. Each limit has a soft and a hard limit.

**List of possible limits returned**
Limit name	Limit description
core	The maximum size of the core file. When 0, not core files are created. When core files are larger than this size, they will be truncated at this size.
totalmem	The maximum size of the memory of the process, in bytes.
virtualmem	The maximum size of the virtual memory for the process, in bytes.
data	The maximum size of the data segment for the process, in bytes.
stack	The maximum size of the process stack, in bytes.
rss	The maximum number of virtual pages resident in RAM
maxproc	The maximum number of processes that can be created for the real user ID of the calling process.
memlock	The maximum number of bytes of memory that may be locked into RAM.
cpu	The amount of time the process is allowed to use the CPU.
filesize	The maximum size of the data segment for the process, in bytes.
openfiles	One more than the maximum number of open file descriptors.
