getw, putw - input and output of words (ints)
int getw(FILE *stream);
int putw(int w, FILE *stream);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
Since glibc 2.3.3:
_SVID_SOURCE || _BSD_SOURCE ||
!(_POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600))
Before glibc 2.3.3:
_SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE
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.
Normally, getw() returns the word read, and putw() returns 0. On error, they return EOF.
SVr4, SUSv2. Not present in POSIX.1-2001.
The value returned on error is also a legitimate data value. ferror(3) can be used to
distinguish between the two cases.
ferror(3), fread(3), fwrite(3), getc(3), putc(3)
