[hardening-discuss] -Wformat and user-defined struct members called printf

[Marcus Better]

Hi,

I'm preparing a package for the upcoming version of ser, the SIP Express
Router, and ran into trouble with -Wformat. The source defines a struct
rpc_t containing a function pointer named "printf":

typedef struct rpc {
/* ... */
    rpc_printf_f printf;
/* ... */
} rpc_t;

This causes compilation errors:

  ratelimit.c:348: error: ‘rpc_t’ has no member named ‘__printf_chk’

Is there a workaround for this, short of renaming the function?

Cheers,

Marcus
