  Python Syntax

            from pmix import *

            foo = {'value': value, 'val_type': type}

where type is the PMIx datatype of value, and value is the associated value expressed in the appropriate Python form for the specified datatype

DESCRIPTION

The pmix_value_t structure is used to represent the value passed to PMIx_Put and retrieved by PMIx_Get, as well as many of the other PMIx functions.

A collection of values may be specified under a single key by passing a pmix_value_t containing an array of type pmix_data_array_t, with each array element containing its own object.
