pvm_export

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.
