Reads the next character from a specified file, and converts it to a
wide-character code.
Format
#include <wchar.h>
wint_t getwc (FILE *file_ptr);
Arguments
- file_ptr
- A pointer to the file to be accessed.
Description
Since getwc is implemented as a macro, a file pointer argument
with side effects (for example getwc (*f++)) might be evaluated
incorrectly. In such a case, use the fgetwc function instead. See
the fgetwc function in this section.
Return Values
| n | The returned character. |
| WEOF | Indicates the end-of-file
or an error. If an error occurs, the function sets errno. For
a list of the values set by this function, see fgetwc in this
section. |
