| 21 | These functions manipulate signal sets stored in a _\bs_\bi_\bg_\bs_\be_\bt_\b__\bt. Either | |
| 22 | s\bsi\big\bge\bem\bmp\bpt\bty\bys\bse\bet\bt() or s\bsi\big\bgf\bfi\bil\bll\bls\bse\bet\bt() must be called for every object of type | |
| 23 | _\bs_\bi_\bg_\bs_\be_\bt_\b__\bt before any other use of the object. | |
| 24 | ||
| 25 | The s\bsi\big\bge\bem\bmp\bpt\bty\bys\bse\bet\bt() function initializes a signal set to be empty. | |
| 26 | ||
| 27 | The s\bsi\big\bgf\bfi\bil\bll\bls\bse\bet\bt() function initializes a signal set to contain all sig- | |
| 28 | nals. | |
| 29 | ||
| 30 | The s\bsi\big\bga\bad\bdd\bds\bse\bet\bt() function adds the specified signal _\bs_\bi_\bg_\bn_\bo to the signal | |
| 31 | set. | |
| 32 | ||
| 33 | The s\bsi\big\bgd\bde\bel\bls\bse\bet\bt() function deletes the specified signal _\bs_\bi_\bg_\bn_\bo from the sig- | |
| 34 | nal set. | |
| 35 | ||
| 36 | The s\bsi\big\bgi\bis\bsm\bme\bem\bmb\bbe\ber\br() function returns whether a specified signal _\bs_\bi_\bg_\bn_\bo is | |
| 37 | contained in the signal set. | |
| 38 | ||
| 39 | These functions are provided as macros in the include file <signal.h>. | |
| 40 | Actual functions are available if their names are undefined (with #undef | |
| 41 | _\bn_\ba_\bm_\be). | |

| 44 | The s\bsi\big\bgi\bis\bsm\bme\bem\bmb\bbe\ber\br() function returns 1 if the signal is a member of the | |
| 45 | set, 0 otherwise. The other functions return 0. | |
