- Name of an environment variable to add to or delete from export list.
The routines pvm_export
are provided for
convenience in editing environment variable PVM_EXPORT,
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.
/* PVM_EXPORT=SHELL:HOME */
/* PVM_EXPORT=SHELL:DISPLAY:TERM */
No error conditions are currently returned by pvm_export and pvm_unexport.
