Hello again,
thank for your answere.

I've found the file ndb_rand.c.
Here is the code:

#include <ndb_rand.h>

static unsigned long next= 1;

* ndb_rand
* constant time, cheap, pseudo-random number generator.
* NDB_RAND_MAX assumed to be 32767
* This is the POSIX example for "generating the same sequence on
* different machines". Although that is not one of our requirements.

int ndb_rand(void)
next= next * 1103515245 + 12345;
return((unsigned)(next/65536) % 32768);

void ndb_srand(unsigned seed)
next= seed;

is this the right code for the function rand()?
What is the starting value when i execute the function without starting value?
