I want to use the crypt_r
function on Mac OS X 10.8.2
#define _GNU_SOURCE
#include <crypt.h>
produces
crypt.h: No such file or directory
Where can I get the crypt.h file from? Or am I including it wrong?
Edited question - concrete example
#include <unistd.h>
#include <stdlib.h>
int main(){
struct crypt_data * data = (struct crypt_data *) malloc(sizeof(struct crypt_data));
char * testhash;
testhash = crypt_r("string", "sa", data);
free(data);
return 0;
}
produces
gcc test.c -Wall
test.c: In function ‘main’:
test.c:5: error: invalid application of ‘sizeof’ to incomplete type ‘struct crypt_data’
test.c:7: warning: implicit declaration of function ‘crypt_r’
test.c:7: warning: assignment makes pointer from integer without a cast
