NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
int pcre2_get_error_message(int errorcode, PCRE2_UCHAR *buffer,
PCRE2_SIZE bufflen);
DESCRIPTION
This function provides a textual error message for each PCRE2
error code. Compilation errors are positive numbers; UTF
formatting errors and matching errors are negative numbers. The
arguments are:
errorcode an error code (positive or negative)
buffer where to put the message
bufflen the length of the buffer (code units)
The function returns the length of the message in code units,
excluding the trailing zero, or the negative error code
PCRE2_ERROR_NOMEMORY if the buffer is too small. In this case,
the returned message is truncated (but still with a trailing
zero). If errorcode does not contain a recognized error code
number, the negative value PCRE2_ERROR_BADDATA is returned.
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.
