Multiple character extraction.

Synopsis

Declared in <bslstl_syncbuf.h>

virtual
streamsize
xsgetn(
    char_type* __s,
    streamsize __n);

Description

Fills __s[0] through __s[] with characters from the input sequence, as if by sbumpc(). Stops when either __n characters have been copied, or when traits::eof() would be copied.

It is expected that derived classes provide a more efficient implementation by overriding this definition.

Return Value

The number of characters assigned.

Parameters

Name

Description

__s

A buffer area.

__n

Maximum number of characters to assign.
