- *_spawnlp(modeflag, filename, arglist) - spawn file and search along PATH
- *
- *Purpose:
- * Spawns a child process.
- * formats the parameters and calls _spawnvp to do the work of searching
- * the PATH environment variable and calling _spawnve. The NULL
- * environment pointer indicates that the new process will inherit the
- * parents process's environment. NOTE - at least one argument must be
- * present. This argument is always, by convention, the name of the file
- * being spawned.
- *
- *Entry:
- * int modeflag - mode of spawn (WAIT, NOWAIT, OVERLAY)
- * only WAIT, OVERLAY currently implemented
- * _TSCHAR *pathname - file to spawn
- * _TSCHAR *arglist - argument list
- * call as _spawnlp(modeflag, path, arg0, arg1, ..., argn, NULL);
- *
- *Exit:
- * returns exit code of child process
- * returns -1 if fails
- *
- *Exceptions:
- *
