DESCRIPTION        top

       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 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). Iferrorcode 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 thepcre2apipage and a description of the POSIX API in thepcre2posix       page.
