Hi.

I've done a bit of research and found that I should be able to use '%ls' in a printf format string to print a wide string value. The problem is I only get the first character printed.

My experimental code looks like this:

  const wchar_t *pString = L"Ello!";

  char buf[100];
  sprintf(buf, "String: %ls", pString);

 

I have set whar_t to be 16 bit.

I'm using CrossStudio for ARM and the selected processor is LPC1788.

 

Is my code wrong or do I need to setup something in the project configuration to make it work?

 

Best regards,

Jan Jørgensen

  Hi Jan,

  Set the Linker > Printf/Scanf > Wide Characters Supported project property to Yes in order to enable printf wide character support.
