LIBUVMEM(3)		     Library Functions Manual		     LIBUVMEM(3)

NAME
     libuvmem -- userspace general purpose resource allocator

SYNOPSIS
     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  docu-
     mentation 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 ignored.

     The library internally uses malloc(3) to allocate structures tracking allo-
     cations.

     The allocator is thread-safe.  Locks for separate	vmem's	are  independent
     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)
