EXPORT(3PVM)							  EXPORT(3PVM)

NAME
       pvm_export, pvm_unexport	- Mark environment variables to	export through
       spawn

SYNOPSIS
       C    int	cc = pvm_export( char *name )
	    int	cc = pvm_unexport( char	*name )

       Fortran	 Not available

PARAMETERS
       name    Name of an environment variable to add to or delete from	export
	       list.

DESCRIPTION
       The  routines  pvm_export and pvm_unexport are provided for convenience
       in editing  environment	variable  PVM_EXPORT,  while  maintaining  the
       colon-separated	list syntax it requires.  The variable can be modified
       by other	means, and at the same time by the pvm_export functions.

       pvm_export checks to see	if a name is already in	PVM_EXPORT before  in-
       cluding	it,  and  exporting a name more	than once is not considered an
       error.  Likewise, pvm_unexport will not complain	if you specify a  name
       not in PVM_EXPORT.

EXAMPLES
       C:
	    /* PVM_EXPORT=SHELL:HOME */
	    pvm_export("DISPLAY");
	    pvm_export("TERM");
	    pvm_unexport("HOME");
	    /* PVM_EXPORT=SHELL:DISPLAY:TERM */

ERRORS
       No  error conditions are	currently returned by pvm_export and pvm_unex-
       port.
