The NetWare API is a C library of function calls. These calls generate NCPs and provide a host application interface to NetWare. Since NetWare is built on the client-server architecture, any request to the NetWare server must be a client request. UnixWare processes link these libraries to gain access to NetWare network operating system services.
A NetWare API layer provides function calls that allow access to NetWare resources such as files, directories, and so on. These services are defined in full in the Section 3nw manual pages.
