    Execute process (using argument list, environment; search path).

    Declaration

    Source position: unix.pp line 125

    function FpExecLP(const PathName: RawByteString; 
                 const S: Array of RawByteString = type string(CP_NONE))
                  : 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.

    Errors

    Extended error information is returned by the FpGetErrno function:

    sys_eacces
    File is not a regular file, or has no execute permission. A component of the path has no search permission.
    sys_eperm
    The file system is mounted noexec.
    sys_e2big
    Argument list too big.
    sys_enoexec
    The magic number in the file is incorrect.
    sys_enoent
