I'm having trouble with the code below with the error on line 5:
error: invalid conversion from
void*
tochar*
I'm using g++ with codeblocks and I tried to compile this file as a cpp file. Does it matter?
#include <openssl/crypto.h>
int main()
{
char *foo = malloc(1);
if (!foo) {
printf("malloc()");
exit(1);
}
OPENSSL_cleanse(foo, 1);
printf("cleaned one byte\n");
OPENSSL_cleanse(foo, 0);
printf("cleaned zero bytes\n");
}
In C++, you need to cast the return of malloc()
char *foo = (char*)malloc(1);
