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

     munmap - remove a mapping

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

     munmap(void *addr, size_t len);

     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.

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

     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.

     madvise(2),  mincore(2),  mprotect(2),  msync(2),  getpagesize(3)

     The munmap() function first appeared in 4.4BSD.
