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  including  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_unexport.
