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.
