Originální popis anglicky: munlockall - reenable paging for calling process

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <sys/mman.h>
 
int munlockall(void);

POPIS / INSTRUKCE

munlockall reenables paging for all pages mapped into the address space of the calling process. Memory locks do not stack, i.e., pages which have been locked several times by calls to mlock or mlockall will be unlocked by a single call to munlockall. Pages which are mapped to several locations or by several processes stay locked into RAM as long as they are locked at least at one location or by at least one process. On POSIX systems on which mlockall and munlockall are available, _POSIX_MEMLOCK is defined in <unistd.h> .

NÁVRATOVÁ HODNOTA

On success, munlockall returns zero. On error, -1 is returned and errno is set appropriately.

CHYBY / ERRORY

EPERM

The calling process has insufficient privilege to call munlockall. Under Linux the CAP_IPC_LOCK capability is required.
