23 Getc returns the next character from the named input stream.
24
25 Getchar() is identical to getc(stdin).
26
27 Fgetc behaves like getc, but is a genuine function, not a macro; it may
28 be used to save object text.
29
30 Getw returns the next int (a 32-bit integer on a VAX-11) from the named
31 input stream. It returns the constant EOF upon end of file or error,
32 but since that is a good integer value, feof and ferror(3S) should be
33 used to check the success of getw. Getw assumes no special alignment
34 in the file.
35
37 clearerr(3S), fopen(3S), putc(3S), gets(3S), scanf(3S), fread(3S),
38 ungetc(3S)
39
41 These functions return the integer constant EOF at end of file, upon
42 read error, or if an attempt is made to read a file not opened by
43 fopen. The end-of-file condition is remembered, even on a terminal,
44 and all subsequent attempts to read will return EOF until the condition
45 is cleared with clearerr(3S).
46
48 Because it is implemented as a macro, getc treats a stream argument
49 with side effects incorrectly. In particular, `getc(*f++);' doesn't
50 work sensibly.
