| .TH PCRE2_SET_RECURSION_MEMORY_MANAGEMENT 3 "24 October 2014" "PCRE2 10.00"
 | |
| .SH NAME
 | |
| PCRE2 - Perl-compatible regular expressions (revised API)
 | |
| .SH SYNOPSIS
 | |
| .rs
 | |
| .sp
 | |
| .B #include <pcre2.h>
 | |
| .PP
 | |
| .nf
 | |
| .B int pcre2_set_recursion_memory_management(
 | |
| .B "  pcre2_match_context *\fImcontext\fP,"
 | |
| .B "  void *(*\fIprivate_malloc\fP)(PCRE2_SIZE, void *),"
 | |
| .B "  void (*\fIprivate_free\fP)(void *, void *), void *\fImemory_data\fP);"
 | |
| .fi

 | |
| .SH DESCRIPTION
 | |
| .rs
 | |
| .sp
 | |
| This function sets the match context fields for custom memory management when
 | |
| PCRE2 is compiled to use the heap instead of the system stack for recursive
 | |
| function calls while matching. When PCRE2 is compiled to use the stack (the
 | |
| default) this function does nothing. The first argument is a match context, the
 | |
| second and third specify the memory allocation and freeing functions, and the
 | |
| final argument is an opaque value that is passed to them whenever they are
 | |
| called. The result of this function is always zero.
 | |

| page and a description of the POSIX API in the
 | |
| .\" HREF
