DESCRIPTION

<>, <>, and <> are (respectively) variants

of <>, <>, and <>.  They differ only in

allowing their caller to pass the variable argument list as a

<> object (initialized by <>) rather than

directly accepting a variable number of arguments.

RETURNS

The return values are consistent with the corresponding functions:

<> returns the number of input fields successfully scanned,

converted, and stored; the return value does not include scanned

fields which were not stored.

If <> attempts to read at end-of-file, the return value

is <>.

If no fields were stored, the return value is <<0>>.

The routines <<_viscanf_r>>, <<_vfiscanf_f>>, and <<_vsiscanf_r>> are

reentrant versions which take an additional first parameter which points to the

reentrancy structure.

PORTABILITY

These are newlib extensions.
