Ft void *
Fn calloc "size_t nmemb" "size_t size"
Ft void *
Fn realloc "void *ptr" "size_t size"
Ft void *
Fn aligned_alloc "size_t alignment" "size_t size"
Ft int
Fn posix_memalign "void **memptr" "size_t alignment" "size_t size"

\"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
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.
\"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Sh SEE ALSO
Xr malloc 3 ,
Xr posix_memalign 3
\"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Sh BUGS
Nm Ns No 's
implementation of
Fn malloc ,
Fn calloc ,
and
Fn realloc
doesn't correctly set
Xr errno 2
on failure.
