Function fanotify_init [src]

Prototype

pub fn fanotify_init(flags: std.os.linux.fanotify.InitFlags, event_f_flags: u32) FanotifyInitError!i32

Parameters

flags: std.os.linux.fanotify.InitFlagsevent_f_flags: u32

Possible Errors

PermissionDenied

ProcessFdQuotaExceeded

SystemFdQuotaExceeded

SystemResources

Unexpected UnexpectedError

The Operating System returned an undocumented error code.

This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.

When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.

UnsupportedFlags

The kernel does not recognize the flags passed, likely because it is an older version.
