# FpExecLE

Execute process (using argument list, environment)

## Declaration

Source position: unix.pp line 78

`function FpExecLE(`
`const PathName: RawByteString;`
`const S: array of RawByteString;`
`MyEnv: ppchar`
`):cint;`

## Description

FpExecLE replaces the currently running program with the program, specified in PathName. S is an array of command options. The executable in PathName must be an absolute pathname. The environment in MyEnv is passed to the program. On success, FpExecLE 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

sys_enotdir
  A component of the path is not a directory.
