Detailed Description

Application layered TCP connection API that executes a proxy-connect.

This file provides a starting layer that executes a proxy-connect e.g. to set up TLS connections through a http proxy.

Function Documentation

◆ altcp_proxyconnect_alloc()

struct altcp_pcb* altcp_proxyconnect_alloc ( void *  arg,
u8_t  ip_type 
)

Allocator function to allocate a proxy connect altcp pcb connecting directly via tcp to the proxy.

The returned pcb is a chain: altcp_proxyconnect - altcp_tcp - tcp pcb

This function is meant for use with altcp_new.

Parameters
argstruct altcp_proxyconnect_config that contains the proxy settings
ip_typeIP type of the connection (lwip_ip_addr_type)

◆ altcp_proxyconnect_new()

struct altcp_pcb* altcp_proxyconnect_new ( struct altcp_proxyconnect_config *  config,
struct altcp_pcb *  inner_pcb 
)

Allocate a new altcp layer connecting through a proxy. This function gets the inner pcb passed.

Parameters
configstruct altcp_proxyconnect_config that contains the proxy settings
inner_pcbpcb that makes the connection to the proxy (i.e. tcp pcb)

◆ altcp_proxyconnect_new_tcp()

struct altcp_pcb* altcp_proxyconnect_new_tcp ( struct altcp_proxyconnect_config *  config,
u8_t  ip_type 
)

Allocate a new altcp layer connecting through a proxy. This function allocates the inner pcb as tcp pcb, resulting in a direct tcp connection to the proxy.

Parameters
configstruct altcp_proxyconnect_config that contains the proxy settings
ip_typeIP type of the connection (lwip_ip_addr_type)

◆ altcp_proxyconnect_tls_alloc()

struct altcp_pcb* altcp_proxyconnect_tls_alloc ( void *  arg,
u8_t  ip_type 
)

Allocator function to allocate a TLS connection through a proxy.

The returned pcb is a chain: altcp_tls - altcp_proxyconnect - altcp_tcp - tcp pcb

This function is meant for use with altcp_new.

Parameters
argstruct altcp_proxyconnect_tls_config that contains the proxy settings and tls settings
ip_typeIP type of the connection (lwip_ip_addr_type)
