+== NAME
+
+nng_stats_get - get statistics snapshot
+
+== SYNOPSIS
+
+[source, c]
+----
+#include <nng/nng.h>
+
+typedef struct nng_stat nng_stat;
+
+int nng_stats_get(nng_stat *statsp)
+----
+
+== DESCRIPTION
+
+The `nng_stat_get()` function attempts to obtain a snapshot of all the
+various diagnostic statistics that are present in the system.
+
+NOTE: The process of collecting statistics is designed to have minimal
+impact on the system, but there is still some impact.
+
+The statistics are organized as a tree, rooted with a parent
+statistic of type `NNG_STAT_SCOPE` that carries no value, and which
+has an empty name.
+This parent statistic is returned through the _statsp_ pointer.
+
+The `<<nng_stat_child.3#,nng_stat_child()>>` and
+`<<nng_stat_next.3#,nng_stat_next()>>` function can be used to
+iterate over the the tree.
+
+When no longer needed, the statistics can be freed with the
+`<<nng_stats_free.3#,nng_stats_free()>>` function, but that
+function must be called only with the root statistic that is returned
+through the _statsp_ pointer.
+
+NOTE: The values of individual statistics are guaranteed to be atomic,
+but due the way statistics are collected there can be discrepancies between them at certain times.
+For example, statistics counting bytes and messages received may not
+reflect the same number of messages, depending on when the snapshot is taken.
+This potential inconsistency arises as a result of optimizations to minimize
+the impact of statistics on actual operations.
+
+NOTE: The names, values, and semantics of statistics provided may change
+from release to release.
+These are provided for informational and debugging use only, and applications
+should not rely on the presence, names, or meanings of any individual statistics.
+
+== RETURN VALUES
+
+This function returns a pointer to the allocated memory on success,
+and `NULL` otherwise.
+
+== ERRORS
+
+[horizontal]
+`NNG_ENOMEM`:: Insufficient free memory to collect statistics.
+`NNG_ENOTSUP`:: Statistics are not supported (compile time option).
