munmap(2)

munmap(2)                        System Calls                        munmap(2)



NAME
       munmap - unmap pages of memory

SYNOPSIS
       #include <sys/mman.h>

       int munmap(void *addr, size_t len);

DESCRIPTION
       The  munmap()  function  removes  the  mappings  for pages in the range
       [addr, addr + len), rounding the len argument up to the  next  multiple
       of the page size as returned by sysconf(3C). If addr is not the address
       of a mapping established by a prior call to mmap(2),  the  behavior  is
       undefined.  After  a  successful call to munmap() and before any subse‐
       quent mapping of the unmapped pages, further references to these  pages
       will  result  in  the  delivery  of  a  SIGBUS or SIGSEGV signal to the
       process.


       The mmap(2) function often performs an implicit munmap().

RETURN VALUES
       Upon successful completion, munmap() returns 0; otherwise,  it  returns
       −1 and sets errno to indicate an error.

ERRORS
       The munmap() function will fail if:

       EINVAL    The  addr  argument  is  not  a  multiple of the page size as
                 returned by sysconf(3C); addresses in the range [addr, addr +
                 len)  are  outside the valid range for the address space of a
                 process; or the len argument has a value less than  or  equal
                 to 0.
