where \fBtype\fP is the PMIx datatype of \fBvalue\fP, and
\fBvalue\fP is the associated value expressed in the appropriate Python form
for the specified datatype
.SH DESCRIPTION
.sp
The \fIpmix_value_t\fP structure is used to represent the value passed to \fIPMIx_Put\fP and retrieved by
\fBPMIx_Get\fP, as well as many of the other PMIx functions.
.sp
A collection of values may be specified under a single key by passing a \fIpmix_value_t\fP containing an array
of type \fIpmix_data_array_t\fP, with each array element containing its own object.
