+== NAME
+
+nng_free - free memory
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+
+void nng_free(void *ptr, size_t size);
+-----------
+
+== DESCRIPTION
+
+The `nng_free()` function deallocates a memory region of size _size_,
+that was previously allocated by <<nng_alloc#,nng_alloc(3)>> or
+<<nng_recv#,nng_recv(3)>> with the `NNG_FLAG_ALLOC` flag.
+
+WARNING: It is very important that _size_ match the allocation size
+used to allocate the memory.
+
+WARNING: Do not attempt to use this function to deallocate memory
+obtained by a call to the system `malloc()` or `calloc()` functions,
+or the {cpp} `new` operator.  Doing so may result in unpredictable
+behavior, including corruption of application memory.
+
+== RETURN VALUES
+
+None.
+
+== ERRORS
+
+None.
