Source position: unix.pp line 80

function FpExecLP(

  const PathName: RawByteString;

  const S: array of RawByteString

):cint;

Description

FpExecLP replaces the currently running program with the program, specified in PathName. S is an array of command options. The executable in PathName is searched in the path, if it isn't an absolute filename. The current environment is passed to the program. On success, FpExecLP does not return.
