2287 : * - No such conversion unavailable.
2288 : * - Character data output was truncated, or numerical data overflowed or lost precision.
2289 : * - In converting character data to one of the numeric types, the string could not be interpreted as a number.
2290 : *
2291 : * Conversion functions are handled in the TDS layer.
2292 : *
2293 : * The main reason for this is that \c ct-lib and \c ODBC (and presumably \c DBI) need
2294 : * to be able to do conversions between datatypes. This is possible because
2295 : * the format of complex data (dates, money, numeric, decimal) is defined by
2296 : * its representation on the wire; thus what we call \c DBMONEY is exactly its
2297 : * format on the wire. CLIs that need a different representation (ODBC?)
2298 : * need to convert from this format anyway, so the code would already be in
2299 : * place.
2300 : *
2301 : * Each datatype is also defined by its Server-type so all CLIs should be
2302 : * able to map native types to server types as well.
2303 : *
2304 : * tds_convert() copies from src to dest and returns the output data length,
2305 : * period. All padding and termination is the responsibility of the API library
2306 : * and is done post-conversion. The peculiar rule in dbconvert() is that
2307 : * a \a destlen of -1 and a \a desttype of \c SYBCHAR means the output buffer
2308 : * should be null-terminated.

8120 : * \ingroup dblib_internal
8121 : * \brief Call client-installed error handler
8122 : *
8123 : * \param dbproc contains all information needed by db-lib to manage communications with the server.
8124 : * \param msgno identifies the error message to be passed to the client's handler.
8125 : * \param errnum identifies the OS error (errno), if any. Use 0 if not applicable.
8126 : * \returns the handler's return code, subject to correction and adjustment for vendor style:
8127 : * - INT_CANCEL The db-lib function that encountered the error will return FAIL.
8128 : * - INT_TIMEOUT The db-lib function will cancel the operation and return FAIL. \a dbproc remains useable.
8129 : * - INT_CONTINUE The db-lib function will retry the operation.
8130 : * \remarks
8131 : * The client-installed handler may also return INT_EXIT. If Sybase semantics are used, this function notifies
8132 : * the user and calls exit(3). If Microsoft semantics are used, this function returns INT_CANCEL.
8133 : *
8134 : * If the client-installed handler returns something other than these four INT_* values, or returns timeout-related
8135 : * value for anything but SYBETIME, it's treated here as INT_EXIT (see above).
8136 : *
8137 : * Instead of sprinkling error text all over db-lib, we consolidate it here,
8138 : * where it can be translated (one day), and where it can be mapped to the TDS error number.
8139 : * The libraries don't use consistent error numbers or messages, so when libtds has to emit
8140 : * an error message, it can't include the text. It can pass its error number to a client-library
8141 : * function, which will interpret it, add the text, call the application's installed handler
8142 : * (if any) and return the handler's return code back to the caller.
8143 : *
8144 : * The call stack may look something like this:
8145 : *
8146 : * -# application
8147 : * -# db-lib function (encounters error)
8148 : * -# dbperror
8149 : * -# error handler (installed by application)
8150 : *
8151 : * The error handling in this case is unambiguous: the caller invokes this function, the client's handler returns its
8152 : * instruction, which the caller receives. Quite often the caller will get INT_CANCEL, in which case it should put its
8153 : * house in order and return FAIL.
8154 : *
8155 : * The call stack may otherwise look something like this:
8156 : *
8157 : * -# application
8158 : * -# db-lib function
8159 : * -# libtds function (encounters error)
8160 : * -# _dblib_handle_err_message
8161 : * -# dbperror
8162 : * -# error handler (installed by application)
8163 : *
8164 : * Because different client libraries specify their handler semantics differently,
8165 : * and because libtds doesn't know which client library is in charge of any given connection, it cannot interpret the
8166 : * raw return code from a db-lib error handler. For these reasons,
8167 : * libtds calls _dblib_handle_err_message, which translates between libtds and db-lib semantics.
8168 : * \sa dberrhandle(), _dblib_handle_err_message().
