Synchronize on-disk copy of quota usages
Usage
#include <sys/quota.h>
int quotactl(QCMD(Q_SYNC, type), const char *_Nullable special, 0, NULL);
#include <sys/quota.h> /* Definition of Q_* constants */ #include <sys/syscall.h> /* Definition of SYS_* constants */ #include <unistd.h>
int syscall(SYS_quotactl_fd, int fd, QCMD(Q_SYNC, type));
Library
Standard C library (libc, -lc)
Overview
Update the on-disk copy of quota usages for a filesystem.
For quotactl(2), if special is NULL, then all filesystems with active quotas are synchronized. quotactl_fd(2) always synchronizes only one filesystem.
Return value
See quotactl(2).
Errors
