I’m following the code from this libcurl example and everything seems to work perfectly as a standalone, so i wanted to make it a function in its own file to reuse in other code.

I added two parameters, one char *addr for the web address and another char *response to retrieve the response from curl, so the template became

extern int curlGet(char *addr, char *response);

and i return the resulting response with a

memcpy(response,chunk.memory,chunk.size+1);

and then i call it on my main file with the following code

int main(void){
    char *tmp=malloc(1);
    curlGet("www.google.com",tmp);
    printf("%sn",tmp);
    //free(tmp);
    return 0;
};

The addr parameter works without a problem, but the tmp one constantly throws a segmentation fault (core dumped), and if i uncomment the free(tmp) i get a

free(): invalid next size (fast)
Aborted (core dumped)

my instincts tell me its something with memory allocation, but i’m too new to c to know why.
