c++ - invalid conversion from `void*' to `char*' when using malloc? -
i'm having trouble code below error on line 5:
error: invalid conversion
void*char*
i'm using g++ codeblocks , tried compile file cpp file. matter?
#include <openssl/crypto.h> int main() { char *foo = malloc(1); if (!foo) { printf("malloc()"); exit(1); } openssl_cleanse(foo, 1); printf("cleaned 1 byte\n"); openssl_cleanse(foo, 0); printf("cleaned 0 bytes\n"); }
in c++, need cast return of malloc()
char *foo = (char*)malloc(1);
