#include <pcre2.h>

int pcre2_set_newline(pcre2_compile_context *ccontext,
  uint32_t value);


This function sets the newline convention within a compile context. This specifies which character(s) are recognized as newlines when compiling and matching patterns. The second argument must be one of:

  PCRE2_NEWLINE_CR        Carriage return only
  PCRE2_NEWLINE_LF        Linefeed only
  PCRE2_NEWLINE_CRLF      CR followed by LF only
  PCRE2_NEWLINE_ANYCRLF   Any of the above
  PCRE2_NEWLINE_ANY       Any Unicode newline sequence
  PCRE2_NEWLINE_NUL       The NUL character (binary zero)

The result is zero for success or PCRE2_ERROR_BADDATA if the second argument is invalid.

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.
