PCRE2 — Perl-compatible regular expressions (revised API)
#include <pcre2.h> int pcre2_get_error_message(interrorcode
, PCRE2_UCHAR *buffer
, PCRE2_SIZEbufflen
);
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 messagebufflen
the length of the buffer (code units)
The function returns the length of the message, 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(3) page and a description of the POSIX API in the pcre2posix(3) page.
