Hi Martin, yes I use fopen() otherwise it can't pass compile :-) . the file are scha_api_rpc.c and scds_fm.c in rgm_president.cc, we can use os:: functions. yet scha_api_rpc.c is c file , and can't use os:: .
In os::, it use "struct _buf *fp;" yet I down't know how to use this *fp.

Edward, The rgmd is userland code. If you are actually modifying rgmd code, the _KERNEL macro will be undefined. Perhaps you could give more details of which source file you are modifying, and what error messages were produced by the compiler. Did you #include <stdio.h> in the file where you attempted this? That is necessary. Also, your example below calls "fileopen" which does not exist. The correct name of the function is "fopen". It is documented in the fopen(3C) man page.
