Portable cross-UNIX header-only shared memory message-passing library using POSIX shmem in C

Use SPI of RPi from any programming languages. This is a layer (service) between SPI and SHM (Shared Memory). The service listens for SHM (Shared Memory) changes to send SHM data to the SPI (MOSI) port and write back returned data from SPI (MOSI) to to SHM. In summary, most programming languages do not have SPI api, but SHM, one of the main components of linux, has read / write functions.
