MUNMAP(2)		   BSD Programmer's Manual		     MUNMAP(2)

NAME
     munmap - remove a mapping

SYNOPSIS
     #include <sys/types.h>
     #include <sys/mman.h>

     int
     munmap(void *addr, size_t len);

DESCRIPTION
     The munmap() system call deletes the mappings for the specified address
     range, and causes further references to addresses within the range to
     generate invalid memory references.

RETURN VALUES
     Upon successful completion, munmap returns zero. Otherwise, a value of -1
     is returned and errno is set to indicate the error.

ERRORS
     munmap() will fail if:

     [EINVAL]	   The addr parameter was not page aligned, the len parameter
		   was negative, or some part of the region being unmapped is
		   not part of the currently valid address space.
