1991 | * my_vfork() - just a vfork(), after setting a flag to record that | |
1992 | * the current script is trying a Unix-style fork/exec. | |
1993 | * | |
1994 | * vms_do_aexec() and vms_do_exec() are called in response to the | |
1995 | * perl 'exec' function. If this follows a vfork call, then they | |
1996 | * call out the the regular perl routines in doio.c which do an | |
1997 | * execvp (for those who really want to try this under VMS). | |
1998 | * Otherwise, they do exactly what the perl docs say exec should | |
1999 | * do - terminate the current script and invoke a new command | |
2000 | * (See below for notes on command syntax.) | |
2001 | * | |
2002 | * do_aspawn() and do_spawn() implement the VMS side of the perl | |
2003 | * 'system' function. | |
2004 | * | |
2005 | * Note on command arguments to perl 'exec' and 'system': When handled | |
2006 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
2007 | * are concatenated to form a DCL command string. If the first arg | |
2008 | * begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
2009 | * the the command string is hrnded off to DCL directly. Otherwise, | |
2010 | * the first token of the command is taken as the filespec of an image | |
2011 | * to run. The filespec is expanded using a default type of '.EXE' and | |
2012 | * the process defaults for device, directory, etc., and the resultant | |
2013 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of | |
2014 | * the command string as parameters. This is perhaps a bit compicated, | |
2015 | * but I hope it will form a happy medium between what VMS folks expect | |
2016 | * from lib$spawn and what Unix folks expect from exec. | |
