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.
