## Detailed Description

Context with the engine state.

The `soap` context should be passed as the first parameter to all gSOAP functions and should only be used by a single thread at a time. Each thread should use a copy of the context created with `soap_copy` or with the `soap::soap` copy constructor.

To allocate a new `soap` context, use one of these three allocators that take `soap_mode` parameters:

struct soap *soap1 = soap_new();
struct soap *soap2 = soap_new1(input_and_output_mode);
struct soap *soap3 = soap_new2(input_mode, output_mode);

Alternatively, use constructors in C++ as follows:

struct soap *soap1();
struct soap *soap2(input_and_output_mode);
struct soap *soap3(input_mode, output_mode);

To copy the `soap` context, for example to be used by another thread, use:

struct soap *soap2 = soap_copy(soap1);

Alternatively, use the copy constructor in C++ as follows:

struct soap *soap2 = new soap(soap1);

To free the `soap` context or a copy of a `soap` context, use:

soap_free(soap1);

To stack-allocate a `soap` context (i.e. as opposed to heap-allocating it as shown above), initialize the `soap` context with one of these three initializers that take `soap_mode` parameters:

struct soap soap1, soap2, soap3;
soap_init(&soap1);
soap_init1(&soap2, input_and_output_mode);
soap_init2(&soap3, input_mode, output_mode);

Alternatively, use constructors in C++:

struct soap soap1();
struct soap soap2(input_and_output_mode);
struct soap soap3(input_mode, output_mode);

Finalization of the `soap` context is automatically done by the C++ destructor. In C, you should finalize a stack-allocated `soap` context before it is reclaimed by the stack:

soap_done(&soap1);

Before freeing or finalizating a `soap` context, you may want to delete all data allocated in managed heap memory with these two calls in this specific order:

soap_destroy(soap1);
soap_end(soap1);

Alternatively, in C++ you can simply invoke one method to perform both calls at once:

soap1.destroy();

## Member Data Documentation

int soap::accept_flags

User-definable `setsockopt` level `SOL_SOCKET` flags (0 by default), when nonzero sets the `soap::socket` flags when accepting a request with `soap_accept` (or the C++ service class `accept` method)

Example:

struct soap *soap = soap_new();
soap->accept_flags = SO_NOSIGPIPE; // no sigpipe (this is not portable)

Other ways to disable sigpipe:

struct soap *soap = soap_new();
soap->socket_flags = MSG_NOSIGNAL;
#include <signal.h>
void sigpipe_handle(int) { }
signal(SIGPIPE, sigpipe_handle);

See also
  `soap::socket_flags`, `soap::connect_flags`, `soap::bind_flags`.

int soap::accept_timeout

User-definable timeout when waiting to accept a request from a client at the server-side with `soap_accept` (or the C++ service class `accept` method), positive timeout values are seconds, negative timeout values are microseconds, zero means no timeout (the value is 0 by default)

Example:

#include "soapH.h"
int main()
{
struct soap *soap = soap_new();
soap->accept_timeout = 3600; // exit loop when no request arrives in one hour
soap->send_timeout = soap_recv_timeout = 5; // 5 seconds max socket stall time (unlimited by default)
soap->transfer_timeout = 30; // 30 seconds max message transfer time (unlimited by default)
soap->recv_maxlength = 1048576; // limit messages received to 1MB (2GB by default)
if (soap_valid_socket(soap_bind(soap, NULL, PORTNUM, BACKLOG)))
{
while (1)
{
if (soap_valid_socket(soap_accept(soap)))
{
if (soap_serve(soap))
soap_print_fault(soap, stderr);
}
else if (soap->errnum) // accept failed, try again after 1 second
{
soap_print_fault(soap, stderr);
sleep(1);
}
else // accept timed out, quit looping
{
break;
}
soap_destroy(soap);
soap_end(soap);
}

unsigned char soap::ipv4_multicast_ttl

User-definable value to set `setsockopt` level `IPPROTO_IP` to `IP_MULTICAST_TTL` when nonzero.

This value is used by the engine for UDP multicast messaging at the client side, sets `setsockopt` level `IPPROTO_IP` to `IP_MULTICAST_TTL` with value `soap::ipv4_multicast_ttl` when nonzero. Requires `WITH_IPV6`.

Example:

struct soap *soap = soap_new();
in_addr_t addr = inet_addr("1.2.3.4"); // optional
soap->send_timeout = 5; // 5 seconds max socket delay
soap->connect_flags = SO_BROADCAST; // required for broadcast
soap->ipv4_multicast_if = &addr; // optional for IPv4, see setsockopt IPPROTO_IP IP_MULTICAST_IF
soap->ipv6_multicast_if = addr; // optional for IPv6 (requires WITH_IPV6), multicast sin6_scope_id
soap->ipv4_multicast_ttl = 1; // optional, see setsockopt IPPROTO_IP, IP_MULTICAST_TTL

Refer to the socket options for `IPPROTO_IP` `IP_MULTICAST_TTL` to limit the lifetime of the packet. Multicast datagrams are sent with a default value of 1, to prevent them to be forwarded beyond the local network. This parameter can be set between 1 to 255.

soap->origin = "http://example.com";
soap->cors_method = "POST"; // request method is POST
soap->cors_header = "..."; // list of comma-separated request headers (may be omitted)
if (soap_connect_command(soap, SOAP_OPTIONS, endpoint, NULL)
|| soap_end_send(soap)

short soap::version

SOAP version (0 = no SOAP, 1 = SOAP 1.1, 2 = SOAP 1.2)

The SOAP version is determined from the SOAP or XML message received. The version is automatically set before sending messages when SOAP 1.1 or SOAP 1.2 namespaces are defined in the `Namespace` table or when SOAP namespaces are omitted from the table. The version can be explicitly set or overruled by calling `soap_set_version`.

float soap::z_ratio_in
