| 21 |
|
|
arguments are: |
| 22 |
|
|
|
| 23 |
|
|
\fIpattern\fR A zero-terminated string containing the |
| 24 |
|
|
regular expression to be compiled |
| 25 |
|
|
\fIoptions\fR Zero or more option bits |
| 26 |
|
|
\fIerrptr\fR Where to put an error message |
| 27 |
|
|
\fIerroffset\fR Offset in pattern where error was found |
| 28 |
|
|
\fItableptr\fR Pointer to character tables, or NULL to |
| 29 |
|
|
use the built-in default |
| 30 |
|
|
|
| 31 |
|
|
The option bits are: |

|
PCRE_CASELESS Do caseless matching |

PCRE must have been compiled with UTF-8 support when PCRE_UTF8 is used. |
| 47 |
|
|
|

|
The yield of the function is a pointer to a private data structure that |
| 49 |
