The function sscanf is the input analog of
printf. sscanf reads
from the string str and interprets it
according to the specified format, which is
described in the documentation for sprintf.
Any whitespace in the format string matches any whitespace in the input
string. This means that even a tab \t in the format string can match a
single space character in the input string.
&reftitle.parameters;
str
The input string being parsed.
format
The interpreted format for str, which is
described in the documentation for sprintf with
following differences:
Function is not locale-aware.
F, g, G and
b are not supported.
D stands for decimal number.
i stands for integer with base detection.
n stands for number of characters processed so far.
...
Optionally pass in variables by reference that will contain the parsed values.
&reftitle.returnvalues;
If only two parameters were passed to this function, the values parsed will
be returned as an array. Otherwise, if optional parameters are passed, the
function will return the number of assigned values. The optional parameters
must be passed by reference.
If there are more substrings expected in the format
than there are available within str,
-1 will be returned.
