Error Handling Rules
Functions expecting an input parameter verify that the parameter is
inside the range and has the correct data type.
•
If a parameter is located outside the range the function returns
INVALID_ARG_RANGE.
•
Functions expecting a pointer for output data as a parameter
verify that the pointer is valid (for example, the pointer must not
be NULL). If the pointer is invalid, the function returns
INVALID_ARG_INVALID_PTR.
•
Functions with a string as a parameter verify that the pointer to
the string is valid. If the pointer is invalid, the function returns
INVALID_ARG_INVALID_STR_PTR.
