We have a C Library which is working fine as a public library. The main feature of the code is to perform a lookup from binary file. The library has ~1k lines of code. We want to enhance the library further with the below requirements. 1. Add cache memory and shared memory search if users OS supporting it. The library performs the I/O read from data file which is a bottleneck. We want to improve the search performance using cached and shared memory method. If OS allowed, users can load the data file into common memory area and reduce the slow file I/O. 2. Make sure the C library and compilation method works in Windows, Linux, Unix, and Mac OS operating system in both 32 bits and 64 bits architecture. 3. Make sure the C library supports PECL, and submit to [login to view URL] repository. 4. This C library has been used in others projects. Therefore the interfaces must not be altered to ensure the compatibility. Knowledge required: C, Linux, memcached, shared memory, PECL, file I/O, binary search

Hi! Adding caching is not complex by itself, but working check under all required platforms take a lot of time and effort, especially if you have no already done test applications for all platforms. PECL also need to be tested strongly. So, if you need good results a lot of work will need to be done.
