EXPORT(3PVM)															      EXPORT(3PVM)

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.
