LIBUVMEM(3)		    Library Functions Manual		   LIBUVMEM(3)

NAME
       libuvmem	-- userspace general purpose resource allocator

SYNOPSIS
       library "libuvmem" #include <sys/vmem.h>

DESCRIPTION
       The  libuvmem is	a general purpose resource allocator.  It is a port of
       the kernel facility of the similar name vmem.

       Refer to	the description	of the kernel allocator	 vmem(9)  to  get  the
       documentation for it.

NOTES
       The  "quantum  cache" feature is	not implemented	for userspace, and the
       quantum and qcache_max arguments	of the vmem_create() function are  ig-
       nored.

       The  library  internally	uses malloc(3) to allocate structures tracking
       allocations.

       The allocator is	thread-safe.  Locks for	separate vmem's	 are  indepen-
       dent between each other.

       The supported flags for the vmem_xalloc() function are

       •   M_NOWAIT

       •   M_FIRSTFIT

       •   M_BESTFIT

       •   M_NEXTFIT

AUTHORS
       See vmem(9) for the history of the kernel allocator.

       The  userspace  port  for  FreeBSD  was	done  by  Konstantin  Belousov
       <kib@FreeBSD.org>.

FreeBSD	ports 15.quarterly     October 16, 2025			   LIBUVMEM(3)
