PCRE2\_SET\_MAX\_PATTERN\_COMPILED\_LENGTH(3) Library Functions Manual PCRE2\_SET\_MAX\_PATTERN\_COMPILED\_LENGTH(3)

# [NAME](#NAME)

PCRE2 - Perl-compatible regular expressions (revised API)

# [SYNOPSIS](#SYNOPSIS)

**#include <pcre2.h>**

```
int pcre2_set_max_pattern_compiled_length(
  pcre2_compile_context *ccontext, PCRE2_SIZE value);
```

# [DESCRIPTION](#DESCRIPTION)

This function sets, in a compile context, the maximum size (in bytes) for the memory needed to hold the compiled version of a pattern that is using this context. The result is always zero. If a pattern that is passed to **pcre2\_compile()** referencing this context needs more memory, an error is generated. The default is the largest number that a PCRE2\_SIZE variable can hold, which is effectively unlimited.

There is a complete description of the PCRE2 native API in the **pcre2api** page and a description of the POSIX API in the **pcre2posix** page.
