Function inotify_add_watchZ [src]

Same as inotify_add_watch except pathname is null-terminated.

Prototype

pub fn inotify_add_watchZ(inotify_fd: i32, pathname: [*:0]const u8, mask: u32) INotifyAddWatchError!i32

Parameters

inotify_fd: i32pathname: [*:0]const u8mask: u32

Possible Errors

AccessDenied

FileNotFound

NameTooLong

NotDir

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.

UserResourceLimitReached

WatchAlreadyExists
