Function Documentation

boolean_t epUtils_isProbablePrime ( ulong oddNumber )

Estimate if a number is a prime number. return <true> if so, <false> else. visibility :: public Parameters: oddNumber   a number Return values: <true>   if it is prime, <false>   else. Definition at line 44 of file epUtils.c.

int epUtils_ptrDeallocatorFunction ( void * ptr )

Generic pointer deallocator function (in fact, it just make a free). visibility :: public Parameters: ptr   the pointer to deallocate Return values: 0   if OK, -1   else. Definition at line 27 of file epUtils.c.

boolean_t epUtils_stringComparisonFunction ( const void * str1, const void * str2 )

A Generic string comparison function (which take care of the case). visibility :: public Parameters: str1   the first string str2   the second string Return values: <true>   if they are equals, <false>   else. Definition at line 72 of file epUtils.c.

uint epUtils_stringHashFunction ( const void * key )

A Generic hash function for string-typed keys. visibility :: public Remarks: 1. hash function used is: h(c) = ( s[0]*b^(n-1) + s[1]*b^(n-2) + ... + s[n-1] ) where: s is the key n its length b = 128 or 256 Parameters: key   the key(a string) Returns: its hash value. Definition at line 95 of file epUtils.c.
