DESCRIPTION
|
|
|
|
|
<<vscanf>>, <<vfscanf>>, and <<vsscanf>> are (respectively) variants
|
|
|
|
|
of <<scanf>>, <<fscanf>>, and <<sscanf>>. They differ only in
|
|
|
|
|
allowing their caller to pass the variable argument list as a
|
|
|
|
|
<<va_list>> object (initialized by <<va_start>>) rather than
|
|
|
|
|
directly accepting a variable number of arguments.
|
|
|
|
|
|
|
|
|
|
RETURNS
|
|
|
|
|
The return values are consistent with the corresponding functions:
|
|
|
|
|
<<vscanf>> returns the number of input fields successfully scanned,
|
|
|
|
|
converted, and stored; the return value does not include scanned
|
|
|
|
|
fields which were not stored.
|
|
|
|

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

is <<EOF>>.

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

The routines <<_vscanf_r>>, <<_vfscanf_f>>, and <<_vsscanf_r>> are

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

reentrancy structure.
