Function Documentation

AXIS2_EXTERN int axutil_rand unsigned int *  seedp  ) 
 

This is reentrant and thread safe simple random number generator function. it is passed an pointer to an unsigned int state value which is used inside the function and changed in each call.

Parameters:
seedp pointer to an unsigned int used as the internal state
Returns:
int int

A random seed value generated based on the time

AXIS2_EXTERN int axutil_rand_with_range unsigned int *  seedp,
int  start,
int  end
 

This is reentrant and thread safe simple random number generator function. it is passed an pointer to an unsigned int state value which is used inside the function and changed in each call. Also it is passed a range in which the random number is selected

Parameters:
seedp pointer to an unsigned int used as the internal state
start start of the range
end end of the range
