hash function for byte sequences

    long strHash(c_string s)

hash function for type "string"

    c_bool strEqual(c_string a, c_string b)

combination of two permutable hash values

## Pre-defined functions for primitive data types

    long primHash(StdCPtr x)

hash function for primitive types like "char","int","pointer"

    c_bool primEqual(StdCPtr a, StdCPtr b)

whether 'a' and 'b' are equal

    c_bool primGreatEqual(StdCPtr a, StdCPtr b)

whether 'a' is greater equal than 'b'

    c_bool primLessEqual(StdCPtr a, StdCPtr b)

whether 'a' is less equal than 'b'

    int primCompare(StdCPtr a, StdCPtr b)

order of 'a' and 'b'

    StdCPtr primCopy(StdCPtr a)

identity

    void primFree(StdCPtr a)

frees a primitive value; i.e. does nothing
