Grapnel Application Programming Interface

During compilation time programs generated by the grp2c utility are linked with several libraries:

Grapnel library. This library implements grapnel version of message passing functions and consists of three different parts. First part is common for both server and client processes. Second is especially for server process and the third is for clients (user processes). These three library is implemented for every supported target systems. Functions, constants, and global variables of the Grapnel Library is called Grapnel API.
Target library. Grapnel library functions use functions of the target system to implement Grapnel API functions.
Other libraries. These libraries, for example slib and gred, implement functionality of other tools developed in SEPP project, or implemet connections between the tools integrating them together.

This chapter of the documentation contains full reference of the Grapnel Library, definitions, global variables, and functions.
