Man page 9 : init_rs_non_canonical

init_rs_non_canonical - Find a matching or allocate a new rs control structure, for fields with non-canonical representation

struct rs_control * init_rs_non_canonical(int  symsize , int (* gffunc ) (int), int  fcr , int  prim , int  nroots );

symsize
    the symbol size (number of bits)

gffunc
    pointer to function to generate the next field element, or the multiplicative identity element if given 0. Used instead of gfpoly if gfpoly is 0

fcr
    the first consecutive root of the rs code generator polynomial in index form

prim
    primitive element to generate polynomial roots

nroots
    RS code generator polynomial degree (number of roots)
