Characters in R are zero terminated (although I couldn't find that in
the R extensions manual). So, you could use:
void dealWithCharacter(char **chaine, int *size){
Rprintf("The string is '%s'\n", chaine[0]);
}

Hi the list,
I include some C code in a R function using .C. The argument is a
character.
I find how to acces to the characters one by one:
--- 8< --- C ------------
void dealWithCharacter(char **chaine, int *size){
int i=0;
for(i=0;i<*size;i++){
Rprintf("Le caractere %i est %c\n",i,chaine[0][i]);
};
}
--- 8< ------ R ---------
ch <- "zerta"
.C("dealWithCharacter",as.character(ch),as.integer(nchar(ch)))
--- 8< ------------------
But is it possible to acces to the full word at once?
