I am using ULTRIX 4.0 (RISC). I have just attempted to build an application which uses RPC. The function "clnt_create()" exists in the header file "/usr/include/rpc/clnt.h" but I can't find the code. Can anyone help? -- Rob Burrowes rob at cs.aukuni.ac.nz. System Admin Computer Science Dept., Auckland University, Private Bag, Auckland, New Zealand
