| .SH DESCRIPTION |
| .rs |
| .sp |
| 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: |
| .sp |
| \fIerrorcode\fP an error code (positive or negative) |
| \fIbuffer\fP where to put the message |
| \fIbufflen\fP the length of the buffer (code units) |
| .sp |
| 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 \fIerrorcode\fP does not contain a recognized error code |
| number, the negative value PCRE2_ERROR_BADDATA is returned. |
