39: PCRE_CONFIG_MATCH_LIMIT and PCRE_CONFIG_MATCH_LIMIT_RECURSION, when it must
40: point to an unsigned long integer. The available codes are:
41: <pre>
42: PCRE_CONFIG_JIT Availability of just-in-time compiler
43: support (1=yes 0=no)

59: 1 CR, LF, or CRLF only
60: PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
61: Threshold of return slots, above which
62: <b>malloc()</b> is used by the POSIX API
63: PCRE_CONFIG_STACKRECURSE Recursion implementation (1=stack 0=heap)
1.1.1.2 ! misho 64: PCRE_CONFIG_UTF16 Availability of UTF-16 support (1=yes
! 65: 0=no); option for <b>pcre16_config()</b>

1.1.1.2 ! misho 72: The function yields 0 on success or PCRE_ERROR_BADOPTION otherwise. That error
! 73: is also given if PCRE_CONFIG_UTF16 is passed to <b>pcre_config()</b> or if
! 74: PCRE_CONFIG_UTF8 is passed to <b>pcre16_config()</b>.
