Declaration

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.

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: The file does not exist.
sys_enomem: Not enough memory for kernel, or to split command line.
sys_enotdir: A component of the path is not a directory.
sys_eloop: The path contains a circular reference (via symlinks).
