Not too different, except string nul terminator is treated the same as
an input file EOF:
"7.19.6.7#2 The sscanf function is equivalent to fscanf, except that
input is obtained from a string (specified by the argument s) rather
than from a stream. Reaching the end of the string is equivalent to
encountering end-of-file for the fscanf function. If copying
takes place between objects that overlap, the behavior is undefined.
Returns
3 The sscanf function returns the value of the macro EOF if an input
failure occurs before any conversion. Otherwise, the sscanf function
returns the number of input items assigned, which can be fewer than
provided for, or even zero, in the event of an early matching
failure."
