NAME
getws, fgetws - get a wide-character string from a stream SYNOPSIS
#include <stdio.h> include <widec.h> wchar_t *getws(wchar_t *ws); #include <stdio.h> include <wchar.h> wchar_t *fgetws(wchar_t *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 condition is encountered. The wide-character string, ws, is then terminated with a null wide-character code. The fgetws() function reads characters from the stream, converts them to the corresponding wide-character codes, and places them in the wchar_t 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 terminated 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 st_atime field of the file associated with stream for update. The st_atime 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. For standard-conforming (see standards(5)) applications, if 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. ERRORS
See fgetwc(3C) for the conditions that will cause fgetws() to fail. ATTRIBUTES

NAME
fgetwc - get a wide-character code from a stream SYNOPSIS
#include <stdio.h> #include <wchar.h> wint_t fgetwc(FILE*stream); DESCRIPTION
The fgetwc() function obtains the next character (if present) from the input stream pointed to by stream, converts that to the correspond- ing wide-character code and advances the associated file position indicator for the stream (if defined). If an error occurs, the resulting value of the file position indicator for the stream is indeterminate. The fgetwc() function may mark the st_atime field of the file associated with stream for update. The st_atime field will be marked for update by the first successful execution of fgetwc(), fgetc(3C), fgets(3C), fgetws(3C), 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 the fgetwc() function returns the wide-character code of the character read from the input stream pointed to by stream converted to a type wint_t. For standard-conforming (see standards(5)) applications, if the end-of-file indicator for the stream is set, fgetwc() returns WEOF whether or not the stream is at end-of-file. If a read error occurs, the error indicator for the stream is set, fgetwc() returns WEOF and sets errno to indicate the error. If an encoding error occurs, the error indicator for the stream is set, fgetwc() returns WEOF, and errno is set to indicate the error. ERRORS
The fgetwc() function will fail if data needs to be read and: EAGAIN The O_NONBLOCK flag is set for the file descriptor underlying stream and the process would be delayed in the fgetwc() opera- tion. EBADF The file descriptor underlying stream is not a valid file descriptor open for reading. EINTR The read operation was terminated due to the receipt of a signal, and no data was transferred. EIO A physical I/O error has occurred, or the process is in a background process group attempting to read from its controlling terminal and either the process is ignoring or blocking the SIGTTIN signal or the process group is orphaned. EOVERFLOW The file is a regular file and an attempt was made to read at or beyond the offset maximum associated with the corresponding stream. The fgetwc() function may fail if: ENOMEM Insufficient storage space is available. ENXIO A request was made of a non-existent device, or the request was outside the capabilities of the device. EILSEQ The data obtained from the input stream does not form a valid character. USAGE
The ferror(3C) or feof(3C) functions must be used to distinguish between an error condition and an end-of-file condition. ATTRIBUTES
