Name of an environment variable to add to or delete from export list. |
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.
C:
|
/* PVM_EXPORT=SHELL:HOME */ | |
|
pvm_export("DISPLAY"); | |
|
pvm_export("TERM"); | |
|
pvm_unexport("HOME"); | |
|
/* PVM_EXPORT=SHELL:DISPLAY:TERM */ |
No error conditions are currently returned by pvm_export and pvm_unexport.
