| .TH PCRE2_JIT_STACK_CREATE 3 "24 March 2017" "PCRE2 10.30" | |
| .SH NAME | |
| PCRE2 - Perl-compatible regular expressions (revised API) | |
| .SH SYNOPSIS | |
| .rs | |
| .sp | |
| .B #include <pcre2.h> | |
| .PP | |
| .nf | |
| .B pcre2_jit_stack *pcre2_jit_stack_create(PCRE2_SIZE \fIstartsize\fP, | |
| .B " PCRE2_SIZE \fImaxsize\fP, pcre2_general_context *\fIgcontext\fP);" | |
| .fi | |

| .SH DESCRIPTION | |
| .rs | |
| .sp | |
| This function is used to create a stack for use by the code compiled by the JIT | |
| compiler. The first two arguments are a starting size for the stack, and a | |
| maximum size to which it is allowed to grow. The final argument is a general | |
| context, for memory allocation functions, or NULL for standard memory | |
| allocation. The result can be passed to the JIT run-time code by calling | |
| \fBpcre2_jit_stack_assign()\fP to associate the stack with a compiled pattern, | |
| which can then be processed by \fBpcre2_match()\fP or \fBpcre2_jit_match()\fP. | |
| A maximum stack size of 512KiB to 1MiB should be more than enough for any | |
| pattern. If the stack couldn't be allocated or the values passed were not | |
| reasonable, NULL will be returned. For more details, see the | |
