| SYNOPSIS | |
| </h2> | |
| <p> | |
| <b>#include <pcre2.h></b> | |
| </p> | |
| <p> | |
| <b>int pcre2_get_error_message(int <i>errorcode</i>, PCRE2_UCHAR *<i>buffer</i>,</b> | |
| <b> PCRE2_SIZE <i>bufflen</i>);</b> | |
| </p> | |
| <h2> | |
| DESCRIPTION | |
| </h2> | |
| <p> | |
| 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: | |
| <pre> | |
| <i>errorcode</i> an error code (positive or negative) | |
| <i>buffer</i> where to put the message | |
| <i>bufflen</i> the length of the buffer (code units) | |
| </pre> | |
| 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 <i>errorcode</i> does not contain a recognized error code | |
| number, the negative value PCRE2_ERROR_BADDATA is returned. | |
