+== NAME
+
+nn_reallocmsg - reallocate message (compatible API)
+
+== SYNOPSIS
+
+[source,c]
+----
+#include <nanomsg/nn.h>
+
+void *nn_reallocmsg(void *old, size_t size);
+----
+
+== DESCRIPTION
+
+The `nn_reallocmsg()` reallocates the message _old_, making it of size _size_.
+
+NOTE: This function is provided for API
+<<nng_compat.3compat#,compatibility>> with legacy _libnanomsg_.
+Consider using the relevant <<libnng.3#,modern API>> instead.
+
+On success, the contents of _old_ are copied into the new message
+(truncating if appropriate), then _old_ is deallocated, and a pointer
+to the new message payload is returned.
+
+On failure, the _old_ message is unchanged, and the value `NULL` is returned
+to the caller.
+
+== RETURN VALUES
+
+This function returns a pointer to message buffer space, or `NULL`
+on failure.
+
+== ERRORS
+
+[horizontal]
+`ENOMEM`:: Insufficient memory is available.
+`EINVAL`:: An invalid _size_ was specified.
+`ETERM`:: The library is shutting down.
