getchar, getwchar

Read a character from standard input.

int getchar();
wint_t getwchar();

Returns the character read. To indicate a read error or end-of-file condition, getchar returns EOF, and getwchar returns WEOF. For getchar, use ferror or feof to check for an error or for end of file.

Each routine reads a single character from stdin and increments the associated file pointer to point to the next character. getchar is the same as _fgetchar, but it is implemented as a function and as a macro.

These functions lock the calling thread and are therefore thread-safe. For a non-locking version, see _getchar_nolock, _getwchar_nolock.
