|| /* Glibc since 2.19: */ _DEFAULT_SOURCE

Описание (Description)
getw() reads a word (that is, an int) from stream. It's provided
for compatibility with SVr4. We recommend you use fread(3)
instead.
putw() writes the word w (that is, an int) to stream. It is
provided for compatibility with SVr4, but we recommend you use
fwrite(3) instead.
Возвращаемое значение (Return value)
Normally, getw() returns the word read, and putw() returns 0. On
error, they return EOF.

Ошибки (баги) (Bugs)
The value returned on error is also a legitimate data value.
ferror(3) can be used to distinguish between the two cases.
