Convert C language data types to ABL data types

When you use an HLC library function to write data to an ABL shared buffer or shared variable, the HLC library function converts the C language data type passed to the function to the appropriate ABL data type.

For example, the prowtbd() HLC library function allows you to write to a date field in a shared buffer. Among the parameters you pass to prowtbd() are year, month, and day, all defined as integer in your C code. The prowtbd() function converts these separate C language integer values into a single ABL date value.
