2286 : * - No such conversion unavailable.
2287 : * - Character data output was truncated, or numerical data overflowed or lost precision.
2288 : * - In converting character data to one of the numeric types, the string could not be interpreted as a number.
2289 : *
2290 : * Conversion functions are handled in the TDS layer.
2291 : *
2292 : * The main reason for this is that \c ct-lib and \c ODBC (and presumably \c DBI) need
2293 : * to be able to do conversions between datatypes. This is possible because
2294 : * the format of complex data (dates, money, numeric, decimal) is defined by
2295 : * its representation on the wire; thus what we call \c DBMONEY is exactly its
2296 : * format on the wire. CLIs that need a different representation (ODBC?)
2297 : * need to convert from this format anyway, so the code would already be in
2298 : * place.
2299 : *
2300 : * Each datatype is also defined by its Server-type so all CLIs should be
2301 : * able to map native types to server types as well.
2302 : *
2303 : * tds_convert() copies from src to dest and returns the output data length,
2304 : * period. All padding and termination is the responsibility of the API library
2305 : * and is done post-conversion. The peculiar rule in dbconvert() is that
2306 : * a \a destlen of -1 and a \a desttype of \c SYBCHAR means the output buffer
2307 : * should be null-terminated.

8119 : * \ingroup dblib_internal
8120 : * \brief Call client-installed error handler
8121 : *
8122 : * \param dbproc contains all information needed by db-lib to manage communications with the server.
8123 : * \param msgno identifies the error message to be passed to the client's handler.
8124 : * \param errnum identifies the OS error (errno), if any. Use 0 if not applicable.
8125 : * \returns the handler's return code, subject to correction and adjustment for vendor style:
8126 : * - INT_CANCEL The db-lib function that encountered the error will return FAIL.
8127 : * - INT_TIMEOUT The db-lib function will cancel the operation and return FAIL. \a dbproc remains useable.
8128 : * - INT_CONTINUE The db-lib function will retry the operation.
8129 : * \remarks
8130 : * The client-installed handler may also return INT_EXIT. If Sybase semantics are used, this function notifies
8131 : * the user and calls exit(3). If Microsoft semantics are used, this function returns INT_CANCEL.
8132 : *
8133 : * If the client-installed handler returns something other than these four INT_* values, or returns timeout-related
8134 : * value for anything but SYBETIME, it's treated here as INT_EXIT (see above).
8135 : *
8136 : * Instead of sprinkling error text all over db-lib, we consolidate it here,
8137 : * where it can be translated (one day), and where it can be mapped to the TDS error number.
8138 : * The libraries don't use consistent error numbers or messages, so when libtds has to emit
8139 : * an error message, it can't include the text. It can pass its error number to a client-library
8140 : * function, which will interpret it, add the text, call the application's installed handler
8141 : * (if any) and return the handler's return code back to the caller.
8142 : *
8143 : * The call stack may look something like this:
8144 : *
8145 : * -# application
8146 : * -# db-lib function (encounters error)
8147 : * -# dbperror
8148 : * -# error handler (installed by application)
8149 : *
8150 : * The error handling in this case is unambiguous: the caller invokes this function, the client's handler returns its
8151 : * instruction, which the caller receives. Quite often the caller will get INT_CANCEL, in which case it should put its
8152 : * house in order and return FAIL.
8153 : *
8154 : * The call stack may otherwise look something like this:
8155 : *
8156 : * -# application
8157 : * -# db-lib function
8158 : * -# libtds function (encounters error)
8159 : * -# _dblib_handle_err_message
8160 : * -# dbperror
8161 : * -# error handler (installed by application)
8162 : *
8163 : * Because different client libraries specify their handler semantics differently,
8164 : * and because libtds doesn't know which client library is in charge of any given connection, it cannot interpret the
8165 : * raw return code from a db-lib error handler. For these reasons,
8166 : * libtds calls _dblib_handle_err_message, which translates between libtds and db-lib semantics.
8167 : * \sa dberrhandle(), _dblib_handle_err_message().
