Detailed Description¶

A destination resolver over lwIP's getaddrinfo, filling the Resolver role for the Sockets API.

What the resolver does through its vtable is the substance:

Resolve asks for an IPv4 address and refuses anything else. A result in another family is reported rather than returned, because the Datagram and Stream beside it send to a sockaddr_in and an address they cannot use would resolve, never deliver, and never say why.
The port is applied to the resolved address, so the caller's port rather than a service name decides it.
A lookup that reaches the network blocks the calling task for as long as the stack's own DNS timeout allows.

Needs an lwIP built with LWIP_SOCKET and LWIP_DNS. Asking for the class without them is a link error.

Draw a resolver from the pool (SOLIDSYSLOG_RESOLVER_POOL_SIZE); an exhausted pool falls back to the shared NullResolver.

struct SolidSyslogResolver * SolidSyslogLwipSocketResolver_Create (
    void
)

Release the pool slot.

void SolidSyslogLwipSocketResolver_Destroy (
    struct SolidSyslogResolver * base
)

The documentation for this class was generated from the following file Platform/LwipSocket/Interface/SolidSyslogLwipSocketResolver.h
