Please read the docs again:
"CALLBACK OPTIONS / CURLOPT_WRITEFUNCTION:
Function pointer that should match the following prototype: size_t function(
void *ptr, size_t size, size_t nmemb, void *userdata); This function gets
called by libcurl as soon as there is data received that needs to be saved. The
size of the data pointed to by ptr is size multiplied with nmemb, it will not
be zero terminated. Return the number of bytes actually taken care of. If that
amount differs from the amount passed to your function, it'll signal an error
to the library. This will abort the transfer and return CURLE_WRITE_ERROR.
"
You shouldn't use strlen.

Rewrite this to:
size_t verif_function(void *ptr, size_t size, size_t nmemb, void *userdata)
{
size_t len = size * nmemb;
if(len>144)
return 0; /* curl will abort with CURLE_WRITE_ERROR */
else
return len; /* ok */
}
