posix_getrlimit — Return info about system resource limits
Descrierea
posix_getrlimit
(
) : array|false
posix_getrlimit() returns an array of information about the current resource's soft and hard limits.
Fiecare resursă are asociată o limită soft și hard. Limita soft este valoarea pe care nucleul o impune pentru resursa corespunzătoare. Limita hard acționează ca un plafon pentru limita soft. Un proces neprivilegiat poate să-și stabilească limita soft la o valoarea între 0 și limita hard, sau poate să-și micșoreze ireversibil limita hard.
Valorile întoarse
Returns an associative array of elements for each limit that is defined. Each limit has a soft and a hard limit.
| 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. |
false on failure.
