fpLstat function

In unit BaseUnix

Return information about the symbolic link itself (doesn't follow the link).

Declaration

pascal
function fpLstat(path: PAnsiChar; Info: PStat): cint

Description

FpLstat gets information about the link specified in Path (or FileName), and stores it in Info, which points to a record of type TStat. Contrary to FpFstat, it stores information about the link, not about the file the link points to. The function returns zero if the call was successful, a nonzero return value indicates failure.

Errors

Extended error information is returned by the FpGetErrno function.

sys_enoent
Path does not exist.
