Please read something about the mlock() and/or mlockall() functions.
The prototype can be found in [/usr/include/]sys/mman.h
You can read there:
/* Guarantee all whole pages mapped by the range [ADDR,ADDR+LEN) to
be memory resident. */
extern int mlock (__const void *__addr, size_t __len) __THROW;
[...]
/* Cause all currently mapped pages of the process to be memory resident
until unlocked by a call to the `munlockall', until the process exits,
or until the process calls `execve'. */
extern int mlockall (int __flags) __THROW;
