This library is also used in Doubango project to provide SigComp +* support for 3GPP IMS and OMA networks. +* This API is designed to efficiently work on embedded systems whith limited memory and low computing power. +* +* As many operators have begun to commercially deploy IMS, the relevance of using SigComp to lower bandwidth usage will come quickly. +* In my own opinion I think that most operators (especially those using RCS) will question how to reduce SIP signaling (registration, billing, presence, messaging …) +* bandwidth usage (who will pay bits?). +* These questions will especially concern using SIP (or all other text-based protocols) in wireless handsets as part of 2.5G, 3G and 4G cellular networks. +* +* SigComp stands for Signaling Compression and has been defined in <a href="http://www.ietf.org/rfc/rfc3320.txt">RFC 3320</a> by the Internet Engineering Task Force (IETF) ROHC working group. +* <br> <br> +* +* @image html SigComp_Architecture.png "SigComp Architecture" +* +* Many application protocols used for multimedia communications are text-based and engineered for bandwidth rich links. As a result the messages have not been optimized in +* terms of size. For example, typical IMS/SIP messages range from a few hundred bytes up to two thousand bytes or more. For this reason, SigComp is mandatory for +* 3GPP IMS netwoks and <a href="http://en.wikipedia.org/wiki/Push_to_Talk_over_Cellular">PoC systems</a>. +* +* SigComp could also be useful for RCS (Rich Communication Suite) networks because of the size of the SIP packets (more than three thousand bytes for presence publication). +* Using SigComp in IMS/RCS context will reduce the round-trip over slow radio links. +* +* @par Supported OS +* +* - Windows XX/Vista (Visual Studio 2005/2008 or Mingw32) +* - Windows Mobile 5 and later (Visual Studio 2005/2008 or Mingw32ce/cegcc toolchain) +* - Symbian S60 (Carbide.c++ v2.0 with S60_3rd_FP2_SDK_v1.1) +* - Google Android +* - Mac OS X, iPhone (Xcode) +* - All Linux, FreeBSD, ...

However if all decompression is to be performed in a single step + (a single call of inflate), the parameter flush should be set to + Z_FINISH. In this case all pending input is processed and all pending + output is flushed; avail_out must be large enough to hold all the + uncompressed data. (The size of the uncompressed data may have been saved + by the compressor for this purpose.) The next operation on this stream must + be inflateEnd to deallocate the decompression state. The use of Z_FINISH + is never required, but can be used to inform inflate that a faster approach + may be used for the single inflate() call. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call.
