.SH DESCRIPTION
|
||
|
|
.ft R
|
||
|
|
MPI_T_pvar_read queries the value of a performance variable identified by the handle
|
||
|
|
specified in \fIhandle\fP in the session specified in \fIsession\fP. The result is
|
||
|
|
stored in the buffer pointed to by \fIbuf\fP. The caller must ensure that the
|
||
|
|
buffer pointed to by \fIbuf\fP is large enough to hold the entire value of the
|
||
|
|
performance variable.
