### DXWarning

Function

Presents a warning message to the user.

Syntax
`
#include <dx/dx.h>
`

void DXWarning(char *message, ...)

Functional Details

The `message` may be a `printf` form string, in which case additional arguments may be needed. The message string should not contain new-line characters, because the `DXWarning` routine formats the message in a manner appropriate to the output medium. For terminal output, this includes prefixing the message with the processor identifier and appending a new line character.

Return Value

None.
