<p><a class="reference internal" href="#mpi-t-pvar-get-info"><span class="std std-ref">MPI_T_pvar_get_info</span></a> can be used to query information from a performance
variable. The function returns the verbosity, class, datatype,
enumeration type, and binding of the queried control variable in the
arguments <em>verbosity</em>, <em>var_class</em>, <em>datatype</em>, <em>enumtype</em>, and <em>bind</em>
respectively. Flags indicating whether the variable is read-only,
continuous, or atomic are returns in <em>readonly</em>, <em>continuous</em>, and
<em>atomic</em> accordingly. See MPI-3 section 14.3.7 for more information. See the
man page for <a class="reference internal" href="MPI_T_cvar_get_info.3.html#mpi-t-cvar-get-info"><span class="std std-ref">MPI_T_cvar_get_info</span></a> for information on variable verbosity.</p>

<em>var_class</em> parameter may be one of the following:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_STATE</span></code>: Variable represents a set of discrete
states that may be described by an enumerator. Variables of this
class must be represented by an MPI_INT. The starting value is the
current state of the variable.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_LEVEL</span></code>: Variable represents the current
utilization level of a resource. Variables of this class must be
represented by an MPI_UNSIGNED, MPI_UNSIGNED_LONG,
MPI_UNSIGNED_LONG_LONG, or MPI_DOUBLE. The starting value is the
current utilization level of the resource.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_SIZE</span></code>: Variable represents the fixed size of a
resource. Variables of this class are represented by an
MPI_UNSIGNED, MPI_UNSIGNED_LONG, MPI_UNSIGNED_LONG_LONG, or
MPI_DOUBLE. The starting value is the current size of the resource.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_PERCENTAGE</span></code>: Variable represents the current
percentage utilization level of a resource. Variables of this class
are represented by an MPI_DOUBLE. The starting value is the current
percentage utilization of the resource.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_HIGHWATERMARK</span></code>: Variable represents the high
watermark of the utilization of a resource. Variables of this class
are represented by an MPI_UNSIGNED, MPI_UNSIGNED_LONG,
MPI_UNSIGNED_LONG_LONG, or MPI_DOUBLE. The starting value is the
current utilization of the resource.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_HIGHWATERMARK</span></code>: Variable represents the low
watermark of the utilization of a resource. Variables of this class

current utilization of the resource.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_COUNTER</span></code>: Variable represents a count of the
number of occurrences of a specific event. Variables of this class

MPI_UNSIGNED_LONG_LONG. The starting value is 0.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_COUNTER</span></code>: Variable represents an aggregated
value that represents a sum of arguments processed during a specific
event. Variables of this class are represented by an MPI_UNSIGNED,
MPI_UNSIGNED_LONG, MPI_UNSIGNED_LONG_LONG, or MPI_DOUBLE. The
starting value is 0.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_TIMER</span></code>: Variable represents the aggregated time
spent by the MPI implementation while processing an event, type of
event, or section of code. Variables of this class are represented
by an MPI_UNSIGNED, MPI_UNSIGNED_LONG, MPI_UNSIGNED_LONG_LONG, or
MPI_DOUBLE. If the variable is represented by an MPI_DOUBLE the
units will be the same as those used by MPI_Wtime(). The starting
value is 0.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">MPI_T_PVAR_CLASS_GENERIC</span></code>: Variable does not fit into any other

<p>This MPI tool interface function returns two strings. This function
takes two argument for each string: a buffer to store the string, and
a length which must initially specify the size of the buffer. If the
length passed is n then this function will copy at most n - 1
characters of the string into the corresponding buffer and set the
length to the number of characters copied - 1. If the length argument
is NULL or the value specified in the length is 0 the corresponding
string buffer is ignored and the string is not returned. For more
information see MPI-3 section 14.3.3.</p>
