| arguments are as follows: |
| <pre> |
| <i>what</i> A code specifying what information is required |
| <i>where</i> Points to where to put the data |
| </pre> |
| The <i>where</i> argument must point to an integer variable, except for |
| PCRE_CONFIG_MATCH_LIMIT and PCRE_CONFIG_MATCH_LIMIT_RECURSION, when it must |
| point to an unsigned long integer. The available codes are: |
| <pre> |
| PCRE_CONFIG_JIT Availability of just-in-time compiler |
| support (1=yes 0=no) |
| PCRE_CONFIG_LINK_SIZE Internal link size: 2, 3, or 4 |
| PCRE_CONFIG_MATCH_LIMIT Internal resource limit |

| 0 all Unicode line endings |
| 1 CR, LF, or CRLF only |
| PCRE_CONFIG_POSIX_MALLOC_THRESHOLD |
| Threshold of return slots, above which |
