copy_req()

copy_req() is using for deep copying the Req object. It is necessary especially for async operations.

Req *copy_req(const Req *original);

Example usage:

typedef struct
{
    Res *res;
} ctx_t;

void handler(Req *req, Res *res)
{
    ctx_t *ctx = malloc(sizeof(*ctx));
    ctx->req = copy_req(req);
}
