## SYNOPSIS

**int chsidfs(const char \****path***, security\_id\_t** *fs\_sid***, security\_id\_t** *f\_sid***);**\
 **int fchsidfs(int** *fd***, security\_id\_t** *fs\_sid***, security\_id\_t** *f\_sid***);**

## DESCRIPTION

The **chsidfs**  and  **fchsidfs** calls may be used to change the SID of a file system using the  *fs\_sid* parameter and/or the SID to use for unlabeled files using the *f\_sid* parameter.  Either SID parameter may be null, in which case the corresponding SID will not be changed.
