man pvm_export () - Mark environment variables to export through spawn
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.
