mi_smallint * mi_scan_projs(MI_AM_SCAN_DESC *scanDesc)

scanDesc

points to the scan descriptor.

Use the return value from mi_scan_nprojs() to determine the number of times to execute mi_scan_projs().

Each of the small integers in the array that this function returns identifies a column by the position of that column in the row descriptor.

See the descriptions of:

• Accessor functions mi_scan_nprojs(), mi_scan_table(), and mi_tab_rowdesc()
• The mi_column_* group of DataBlade API functions and the row descriptor (MI_ROW_DESC data structure) in the IBM Informix: DataBlade API Programmer's Guide
