# inode\_permission(9)

Check for access rights to a given inode

## NAME

inode\_permission - Check for access rights to a given inode

## SYNOPSIS

**int inode\_permission(struct inode \*** *inode***, int** *mask***);**

## ARGUMENTS

*inode*

Inode to check permission on

*mask*

Right to check for (**MAY\_READ**, **MAY\_WRITE**, **MAY\_EXEC**)

## DESCRIPTION

Check for read/write/execute permissions on an inode. We use fs\[ug\]id for this, letting us set arbitrary permissions for filesystem access without changing the “normal” UIDs which are used for other things.

When checking for MAY\_APPEND, MAY\_WRITE must also be set in *mask*.
