[pgbr-geral] Funcao em C reverse +

Fri, 21 Aug 2009 12:13:35 -0700 

Estou usando a funcao reverse em C  --
http://blog.frosties.org/post/2007/08/28/Fonction-reverse-C-avec-PostgreSQL
e estou adicionando a funcao  char *replace(const char *s, const char *old,
const char *new)

Acrescentei  char * str;

    str_in = PG_GETARG_VARCHAR_P_COPY(0); 
    len = (int) (VARSIZE(str_in) - VARHDRSZ); 

    str_out = (VarChar *)palloc(VARSIZE(str_in)); 
    SET_VARSIZE(str_out, VARSIZE(str_in)); 

    pg_verifymbstr(VARDATA(str_in), len, false); 

    --Aqui acrescentei
     str =(char *)malloc(sizeof(len));

     strncpy(str ,VARDATA(str_in), len );
 
     str = replace(str, "0A12","RRJA");
 
     strncpy(VARDATA(str_in),str, len);

Qdo retorna a função retorna falta caracters ? Tem algum jeito de fazer
VarChar receber o char * e vice versa ?
