| 38 | .SH DESCRIPTION | |
| e511ffb6 | 39 | .BR re_comp () |
| fea681da MK |
40 | is used to compile the null-terminated regular expression pointed to by |
| 41 | .IR regex . | |
| 42 | The compiled pattern occupies a static area, the pattern buffer, | |
| 43 | which is overwritten by subsequent use of | |
| e511ffb6 | 44 | .BR re_comp (). |
| fea681da MK |
45 | If |
| 46 | .I regex | |
| 8478ee02 | 47 | is NULL, |
| fea681da MK |
48 | no operation is performed and the pattern buffer's contents are not |
| 49 | altered. | |
| 50 | ||
| e511ffb6 | 51 | .BR re_exec () |
| fea681da MK |
52 | is used to assess whether the null-terminated string pointed to by |
| 53 | .I string | |
| 54 | matches the previously compiled | |
| 55 | .IR regex . | |
| 56 | .SH "RETURN VALUE" | |
| e511ffb6 | 57 | .BR re_comp () |
| 8478ee02 | 58 | returns NULL on successful compilation of |
| fea681da MK |
59 | .I regex |
| 60 | otherwise it returns a pointer to an appropriate error message. | |
| 61 | ||
| e511ffb6 | 62 | .BR re_exec () |
| fea681da MK |
63 | returns 1 for a successful match, zero for failure. |
