The wsscanf() function reads Process Code characters from the Process Code string s, interprets them according to the format, and stores the results in its arguments. It expects, as arguments, a control string format, and a set of pointer arguments indicating where the converted input should be stored. The results are undefined if there are insufficient args for the format. If the format is exhausted while args remain, the excess args are simply ignored.

The conversion specifications and behavior of wsscanf() are the same as the regular sscanf(3C) function except that the source is a Process Code string for wsscanf() and on Extended Unix Code (EUC) character string for sscanf(3C).

Upon successful completion, wsscanf() returns the number of characters matched. Otherwise, it returns a negative value.
