Synopsis:
#include <qdb/qdb.h>
char *qdb_vmprintf( const char* format, va_list arg );
Arguments:
- format
- A pointer to a formatting string to process. This string
determines what additional arguments you need to provide. For more
information, see printf() in the QNX Neutrino C Library Reference.
- arg
- A variable-argument list of the additional arguments. You must have
initialized this list with the va_start() macro.
Library:
qdb

not printf()), see qdb_mprintf().
