NAME

kmem_free − free previously allocated kernel memory .IX \f4kmem_free\fP(D3DK)

SYNOPSIS

#include <sys/types.h>
#include <sys/kmem.h>
void kmem_free(void ∗addr, size_t size);

ARGUMENTS

addrAddress of the allocated memory to be returned.  addr must specify the same address that was returned by the corresponding call to kmem_alloc(D3DK) or kmem_zalloc(D3DK) which allocated the memory. 

sizeNumber of bytes to free.  The size parameter must specify the same number of bytes as was allocated by the corresponding call to kmem_alloc or kmem_zalloc. 

DESCRIPTION

kmem_free returns size bytes of previously allocated kernel memory.  The addr and size arguments must specify exactly one complete area of memory that was allocated by a call to kmem_alloc or kmem_zalloc (that is, the memory cannot be freed piecemeal). 

RETURN VALUE

None. 

LEVEL

Base or Interrupt. 

NOTES

Does not sleep. 

Driver-defined basic locks, read/write locks, and sleep locks may be held across calls to this function.
