This requires compiler support for 54 * the renamed functions (introduced in gcc-2.5.3; previous versions 55 * only supported *jmp with 0 or 1 leading underscores). 56 * 57 * Use sigprocmask() instead of sigblock() and sigsetmask(), and 58 * check for and handle errors. 59 * 60 * Restore _all_ the registers and the signal mask atomically. Can 61 * use sigreturn() if sigreturn() works. 62 */ 63 |
