This is my first try making a C HTTP client that will:

1. Receive some data from a WEB API:

Using CURL_EASY functions from libcurl.h to make the request. It works realy well.

I used the prototype WRITEDATA function in the libcurl documentation to store the the data e return a pointer that will be used in the next step.

struct memory { char *response; size_t size; };

static size_t cb(void *data, size_t size, size_t nmemb, void *clientp) { size_t realsize = size * nmemb; struct memory *mem = (struct memory *)clientp;

char ptr = realloc(mem->response, mem->size + realsize + 1); if(!ptr) return 0; / out of memory! */

mem->response = ptr; memcpy(&(mem->response[mem->size]), data, realsize); mem->size += realsize; mem->response[mem->size] = 0;

return realsize;

Since I'm trying to learn C syntax, a lot of time was spend to understand how that function works.

2. Parse the Json content;

3. Save the data in a MYSQL database.
