Message The function "<routine name>" is a builtin function reserved to the compiler, and cannot be used with #pragma function. The function will continue to be treated as a builtin. Description A function identifier specified in a #pragma function directive is the name of a builtin function. These functions cannot be explicitly disabled, they are always handled as builtin functions. User Action Remove the inappropriate use of the pragma, and change the name of the function in order to have it treated as an ordinary callable function.
