To get around this problem 88 * the glibc always had its own definitions for the sigaction structures. 89 * 90 * The current struct sigaction uapi definition below is suitable for the 91 * sys_rt_sigaction system call only. 92 */ 93struct sigaction { 94 union { 95 __sighandler_t _sa_handler; 96 void (*_sa_sigaction)(int, struct siginfo *, void *); 97 } _u; 98 unsigned long sa_flags; 99 void (*sa_restorer)(void); 100 sigset_t sa_mask; 101}; 102 103#define sa_handler _u._sa_handler 104#define sa_sigaction _u._sa_sigaction 105 106#endif /* __KERNEL__ */ 107 108typedef struct sigaltstack { 109 void __user *ss_sp; 110 int ss_flags; 111 __kernel_size_t ss_size; 112} stack_t; 113 114 115#endif /* _UAPI_ASMS390_SIGNAL_H */
