Garante que há espaço na área para colocar pelo menos um personagem por poupar algum subseqüência inicial de caracteres começando
pbase() para a seqüência de saída e atualizar os ponteiros para a área de saída (se necessário). Se não é ch traits::eof() (ie traits::eq_int_type(c, traits::eof()) != true), que o mesmo seja colocado para a área de saída, ou directamente guardado a sequência de saída.Original:
Ensures that there space at the put area for at least one character by saving some initial subsequence of characters starting at
pbase() to the output sequence and updating the pointers to the output area (if needed). If ch is not traits::eof() (i.e. traits::eq_int_type(c, traits::eof()) != true), it is either put to the output area or directly saved to the output sequence.The text has been machine-translated via Google Translate.
