# lrd_data_info

Example: lrd_data_info | Statement Handling Functions

Gets I/O descriptor information. (CtLib only)

    LRDRET lrd_data_info( LRD_CURSOR *mptCursor, unsigned int muiColNum, unsigned long muliIODescNum, char *mpszReqSpec, int miDBErrorSeverity);

mptCursor | A pointer to an LRD_CURSOR structure.
muiColNum | The column number of the requested data (one-based).
muliIODescNum | The I/O descriptor number (one-based, greater than 0).
mpszReqSpec | A pointer to the string containing the request specification.
miDBErrorSeverity | The Error Severity Levels of a failure in a database routine.

The lrd_data_info function gets I/O descriptor information based on a request specification. The request specification string is a null-terminated string containing semicolon-separated pairs of <keyword>=<value> specification.

Currently, keywords are not supported and the string must be empty (""). Only a "Get" operation is therefore supported.

For more details refer to the Function Header File lrd.h in the include directory.
