DESCRIPTION

23       The  routines  pvm_export and pvm_unexport are provided for convenience
24       in editing  environment  variable  PVM_EXPORT,  while  maintaining  the
25       colon-separated  list syntax it requires.  The variable can be modified
26       by other means, and at the same time by the pvm_export functions.
27
28       pvm_export checks to see if a name  is  already  in  PVM_EXPORT  before
29       including  it, and exporting a name more than once is not considered an
30       error.  Likewise, pvm_unexport will not complain if you specify a  name
31       not in PVM_EXPORT.

EXAMPLES

35       C:
36            /* PVM_EXPORT=SHELL:HOME */
37            pvm_export("DISPLAY");
38            pvm_export("TERM");
39            pvm_unexport("HOME");
40            /* PVM_EXPORT=SHELL:DISPLAY:TERM */
