Wrapper for stat() system call.

Warning
on Linux (an maybe on others) a stat() of an nfs mounted (remote) file does never timeout and cannot be interrupted! So e.g. Foam::ping first and hope nfs is running.

Constructor & Destructor Documentation

◆ fileStat() [1/3]

fileStat ( )

Empty constructor.

Definition at line 43 of file fileStat.C.

◆ fileStat() [2/3]

fileStat ( const fileName fName,
const bool  checkVariants = true,
const bool  followLink = true,
const unsigned int  maxTime = 0 
)

Construct from components.

followLink : in case of link get status of pointed-to file maxTime : time out

◆ fileStat() [3/3]

fileStat ( Istream is)

Construct from Istream.
