hi! 1.i find there is l4_ipc_error( ) ops like that in .h files,but where can i find the implementation of that func?
As the function is inlined, its implementation is in the very same header file (pkg/l4sys/include/ipc.h). It just returns the error code, stored in the utcb, which was set during IPC.
2.l4_ipc_error( ),return 4,i look up in l4re document it means L4_ENOT_EXISTENT.but how can i solve that?
The documentation in the header file (pkg/l4sys/include/ipc.h) is quite clear about the error source:
L4_IPC_ENOT_EXISTENT = 0x04, /**< Non-existing destination or source.
could you please give us a minimal code example (including the lua script and both communcation partners) that causes this? You communication partner has probably terminated or something like that.
