## Function Documentation

unsigned char* tds7_crypt_pass | ( | const unsigned char * | clear_pass,
|  | size_t | len,
|  | unsigned char * | crypt_pass |
| ) |  |  |

tds7_crypt_pass() -- 'encrypt' TDS 7.0 style passwords.

the calling function is responsible for ensuring crypt_pass is at least 'len' characters

int tds_bcp_send_record | ( | TDSSOCKET * | tds,
|  | TDSBCPINFO * | bcpinfo,
|  | tds_bcp_get_col_data | get_col_data,
|  | tds_bcp_null_error | null_error,
|  | int | offset |
| ) |  |  |

Returns:
  TDS_SUCCEED or TDS_FAIL.

char* tds_get_homedir | ( | void |  | ) |

Get user home directory.

Returns:
  home directory or NULL if error. Should be freed with free

TDSLOCALE* tds_get_locale | ( | void |  | ) |

Get locale information.

Returns:
  allocated structure with all information or NULL if error

int tds_iconv_alloc | ( | TDSSOCKET * | tds | ) |

Allocate iconv stuff.

Returns:
  0 for success

void tds_set_column_type | ( | TDSSOCKET * | tds,
|  | TDSCOLUMN * | curcol,
|  | int | type |
| ) |  |  |

Set type of column initializing all dependency.

Parameters:

  | curcol | column to set
  | type | type to set

void tds_set_param_type | ( | TDSSOCKET * | tds,
|  | TDSCOLUMN * | curcol,
|  | TDS_SERVER_TYPE | type |
| ) |  |  |

Set type of column initializing all dependency.

Parameters:

  | tds | state information for the socket and the TDS protocol
  | curcol | column to set
  | type | type to set

void tds_set_server | ( | TDSLOGIN * | tds_login,
|  | const char * | server |
| ) |  |  |

Set the servername in a TDSLOGIN structure.

Normally copies server into tds_login. If server does not point to a plausible name, the environment variables TDSQUERY and DSQUERY are used, in that order. If they don't exist, the "default default" servername is "SYBASE" (although the utility of that choice is a bit murky).

Parameters:

  | tds_login | points to a TDSLOGIN structure
  | server | the servername, or NULL, or a zero-length string

Todo:
  open the log file earlier, so these messages can be seen.

TDS_STATE tds_set_state | ( | TDSSOCKET * | tds,
|  | TDS_STATE | state |
| ) |  |  |

Set state of TDS connection, with logging and checking.

Parameters:

  | tds | state information for the socket and the TDS protocol
  | state | the new state of the connection, cf. TDS_STATE.

Returns:
  the new state, which might not be state.

char* tds_timestamp_str | ( | char * | str,
|  | int | maxlen |
| ) |  |  |

strftime(str, maxlen - 6, "%Y-%m-%d %H:%M:%S", tm);

int tds_version | ( | TDSSOCKET * | tds_socket,
|  | char * | pversion_string |
| ) |  |  |

Returns the version of the TDS protocol in effect for the link as a decimal integer.

Typical returned values are 42, 50, 70, 80. Also fills pversion_string unless it is null. Typical pversion_string values are "4.2" and "7.0".

void tdsdump_col | ( | const TDSCOLUMN * | col | ) |

Write a column value to the debug log.

Parameters:

  | file | name of the log file
  | col | column to dump

void tdsdump_dump_buf | ( | const char * | file,
|  | unsigned int | level_line,
|  | const char * | msg,
|  | const void * | buf,
|  | size_t | length |
| ) |  |  |

Dump the contents of data into the log file in a human readable format.

Parameters:

  | msg | message to print before dump
  | buf | buffer to dump
  | length | number of bytes in the buffer

void tdsdump_log | ( | const char * | file,
|  | unsigned int | level_line,
|  | const char * | fmt,
|  |  | ... |
| ) |  |  |

Write a message to the debug log.

Parameters:

  | file | name of the log file
  | level_line | kind of detail to be included
  | fmt | printf-like format string

void tdsdump_on | ( | void |  | ) |

Turn logging back on.

You must call tdsdump_open() before calling this routine.

int tdsdump_open | ( | const char * | filename | ) |

Create and truncate a human readable dump file for the TDS traffic.

The name of the file is specified by the filename parameter. If that is given as NULL or an empty string, any existing log file will be closed.

Returns:
  true if the file was opened, false if it couldn't be opened.

int tdserror | ( | const TDSCONTEXT * | tds_ctx,
|  | TDSSOCKET * | tds,
|  | int | msgno,
|  | int | errnum |
| ) |  |  |

Call the client library's error handler (for library-generated errors only).

The client library error handler may return: TDS_INT_CANCEL -- Return TDS_FAIL to the calling function. For TDSETIME, closes the connection first. TDS_INT_CONTINUE -- For TDSETIME only, retry the network read/write operation. Else invalid. TDS_INT_TIMEOUT -- For TDSETIME only, send a TDSCANCEL packet. Else invalid.

These are Sybase semantics, but they serve all purposes. The application tells the library to quit, fail, retry, or attempt to cancel. In the event of a network timeout, a failed operation necessarily means the connection becomes unusable, because no cancellation dialog was concluded with the server.

It is the client library's duty to call the error handler installed by the application, if any, and to interpret the installed handler's return code. It may return to this function one of the above codes only. This function will not check the return code because there's nothing that can be done here except abort. It is merely passed to the calling function, which will (we hope) DTRT.

Parameters:

  | tds_ctx | points to a TDSCONTEXT structure
  | tds | the connection structure, may be NULL if not connected
  | msgno | an enumerated libtds msgno, cf. tds.h
  | errnum | the OS errno, if it matters, else zero

Returns:
  client library function's return code
