SYNOPSIS
#include <nng/transport/inproc/inproc.h>
int nng_inproc_register(void);
DESCRIPTION
The inproc transport provides communication support between nng sockets within the same process. This may be used as an alternative to slower transports when data must be moved within the same process.
This transport tries hard to avoid copying data, and thus is very light-weight.
Registration
The inproc transport is generally built-in to the nng core, so no extra steps to use it should be necessary.
URI Format
This transport uses URIs using the scheme inproc://
, followed by
an arbitrary string of text, terminated by a NUL
byte.
Multiple URIs can be used within the same application, and they will not interfere with one another.
Two applications may also use the same URI without interfering with each other, and they will be unable to communicate with each other using that URI.
Socket Address
When using an nng_sockaddr
structure,
the actual structure is of type
nng_sockaddr_inproc
.
Transport Options
The inproc transport has no special options.
While inproc accepts the option
NNG_OPT_RECVMAXSZ for
compatibility, the value of the option is ignored with no enforcement.
As inproc peers are in the same address space, they are implicitly trusted,
and thus it makes no sense to spend cycles protecting a program from itself.
