* include/resolv.h (res_pquery): Remove declaration.
|
||||
* resolv/res_data.c (fp_nquery, fp_query, p_query): Remove
|
||||
functions.
|
||||
(_res_opcodes): Remove variable.
|
||||
* resolv/res_debug.c (do_section): Receive pfcode instead of
|
||||
statp.
|
||||
(res_pquery): Rename ...
|
||||
(fp_nquery): to this function. Skip unnecessary _res
|
||||
initialization.
|
||||
(fp_query, p_query, _res_opcodes): Copied from resolv/res_data.c.
