std::basic_streambuf::snextc

性病：基本[医]Streambuf：：snextc

int_type snextc(​​

将输入序列向前推进一个字符并读取一个字符。

函数调用sbumpc()以推进输入序列。如果该函数返回Traits::eof()意味着输入序列已经耗尽，并且uflow()无法检索更多数据，Traits::eof()会被归还。不然的话sgetc()是为了读取字符而调用的。

参数

%280%29

返回值

下一个字符的值。如果输入序列已经耗尽，Traits::eof()会被归还。

例

另见

sgetcreads one character from the input sequence without advancing the sequence (public member function)
sbumpcreads one character from the input sequence and advances the sequence (public member function)
