+.Sh DESCRIPTION
+The
+.Nm
+library provides a lower-performance but smaller-size drop-in
+replacement for the standard
+.Xr malloc 3
+family of functions provided by
+.Lb libc ,
+as well as internal hooks for
+.Xr fork 2
+safety in multithreaded programs.
+.Pp
+Programs can be statically linked with
+.Li -lbsdmalloc
+for smaller code footprint, at a higher cost to run-time performance
+and scalability and limited diagnostics.

+implementation of
+.Fn malloc ,
+.Fn calloc ,
+and
+.Fn realloc
+doesn't correctly set
+.Xr errno 2
+on failure.
