Standard C Library Functions getws(3C)
NAME
getws, fgetws - get a wide-character string from a stream
SYNOPSIS
#include
include
wchart *getws(wchart *ws);
#include
include
wchart *fgetws(wchart *restrict ws, int n, FILE *restrict stream);
DESCRIPTION
The getws() function reads a string of characters from the
standard input stream, stdin, converts these characters to
the corresponding wide-character codes, and writes them to
the array pointed to by ws, until a newline character is
read, converted and transferred to ws or an end-of-file con-
dition is encountered. The wide-character string, ws, is
then terminated with a null wide-character code.
The fgetws() function reads characters from the stream, con-
verts them to the corresponding wide-character codes, and
places them in the wchart array pointed to by ws until n-1
characters are read, or until a newline character is read,
converted and transferred to ws, or an end-of-file condition
is encountered. The wide-character string, ws, is then ter-
minated with a null wide-character code.
If an error occurs, the resulting value of the file position
indicator for the stream is indeterminate.
The fgetws() function may mark the statime field of the
file associated with stream for update. The statime field
will be marked for update by the first successful execution
of fgetc(3C), fgets(3C), fgetwc(3C), fgetws(), fread(3C),
fscanf(3C), getc(3C), getchar(3C), gets(3C), or scanf(3C)
using stream that returns data not supplied by a prior call
to ungetc(3C) or ungetwc(3C).
RETURN VALUES
Upon successful completion, getws() and fgetws() return ws.
If the stream is at end-of-file, the end-of-file indicator
for the stream is set and fgetws() returns a null pointer.

the end-of-file indicator for the stream is set, fgetws()
returns a null pointer whether or not the stream is at end-
of-file. If a read error occurs, the error indicator for the
stream is set and fgetws() returns a null pointer and sets
errno to indicate the error.
