Mixing numbered and unnumbered argument specifications in a format string can have unpredictable results. Referencing numbered arguments in the argument list from the format string more than once can have unpredictable results. An optional decimal integer that specifies the maximum field width. An optional character that sets the size of the receiving variable for some flags. A conversion code that specifies the type of conversion to be applied.
Assignment suppression provides a way to describe an input field to be skipped.
The input field is a string of nonwhite space characters. It extends to the next inappropriate character or until the field width, if specified, is exhausted. The conversion code indicates how to interpret the input field. The corresponding Pointer parameter must be a restricted type. Do not specify the Pointer parameter for a suppressed field.
