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;
