/***
|
|
*int _execl(filename, arglist) - execute a file with arg list
|
|
*
|
|
*Purpose:
|
|
* Transform the argument list so it is a vector, then pass its address
|
|
* to execve. Use a pointer to the default environment vector.
|
|
*
|
|
*Entry:
|
|
* _TSCHAR *filename - file to execute
|
|
* _TSCHAR *arglist - list of arguments
|
|
* call as _execl(path, arg0, arg1, ..., argn, NULL);
|
|
*
|
|
*Exit:
|
|
* destroys the calling process, hopefully
|
|
* returns -1 if fails
|
|
*
|
|
*Exceptions:
|
|
*
