DESCRIPTION
<<iscanf>>, <<fiscanf>>, and <<siscanf>> are the same as
<<scanf>>, <<fscanf>>, and <<sscanf>> respectively, only that
they restrict the available formats to non-floating-point
format specifiers.
The routines <<_iscanf_r>>, <<_fiscanf_r>>, and <<_siscanf_r>> are reentrant
versions of <<iscanf>>, <<fiscanf>>, and <<siscanf>> that take an additional
first argument pointing to a reentrancy structure.
RETURNS
<<iscanf>> returns the number of input fields successfully
scanned, converted and stored; the return value does
not include scanned fields which were not stored.
If <<iscanf>> attempts to read at end-of-file, the return
value is <<EOF>>.
If no fields were stored, the return value is <<0>>.
PORTABILITY
<<iscanf>>, <<fiscanf>>, and <<siscanf>> are newlib extensions.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
