bdflush
BDFLUSH(2) Linux Programmer's Manual BDFLUSH(2)NAME
bdflush - start, flush, or tune buffer-dirty-flush daemon
SYNOPSIS
#include <sys/kdaemon.h>
int bdflush(int func, long *address);
int bdflush(int func, long data);
DESCRIPTION
bdflush() starts, flushes, or tunes the buffer-dirty-flush daemon. Only a privileged process (one with the CAP_SYS_ADMIN capability) may
call bdflush().
If func is negative or 0, and no daemon has been started, then bdflush() enters the daemon code and never returns.
If func is 1, some dirty buffers are written to disk.
If func is 2 or more and is even (low bit is 0), then address is the address of a long word, and the tuning parameter numbered (func-2)/2
is returned to the caller in that address.
If func is 3 or more and is odd (low bit is 1), then data is a long word, and the kernel sets tuning parameter numbered (func-3)/2 to that
value.
The set of parameters, their values, and their valid ranges are defined in the kernel source file fs/buffer.c.
RETURN VALUE
If func is negative or 0 and the daemon successfully starts, bdflush() never returns. Otherwise, the return value is 0 on success and -1
on failure, with errno set to indicate the error.
ERRORS
EBUSY An attempt was made to enter the daemon code after another process has already entered.
EFAULT address points outside your accessible address space.
EINVAL An attempt was made to read or write an invalid parameter number, or to write an invalid value to a parameter.
EPERM Caller does not have the CAP_SYS_ADMIN capability.
CONFORMING TO
bdflush() is Linux-specific and should not be used in programs intended to be portable.
