Name
       getc, getchar, fgetc, getw - get character or word from stream

Syntax
       #include <stdio.h>

       int getc(stream)
       FILE *stream;

       int getchar()

       int fgetc(stream)
       FILE *stream;

       int getw(stream)
       FILE *stream;

Description
       The function returns the next character from the named input stream.

       The function is identical to (stdin).

       The function behaves like but is a genuine function, not a macro.  It may be used to save object text.

       The  function returns the next word (in a 32-bit integer on a VAX-11 or MIPS machine) from the named input stream.  It returns the constant
       EOF upon end of file or error, but since that is a good integer value, feof and should be used to check the success of The assumes no  spe-
       cial alignment in the file.

Restrictions
       Because it is implemented as a macro, treats a stream argument with side effects incorrectly.  In particular, `getc(*f++);' doesn't work as
       expected.

Diagnostics
       These functions return the integer constant EOF at end of file or upon read error.

       A stop with message, `Reading bad file', means an attempt has been made to read from a stream that has not been opened for reading by

NAME

       getc, getchar, fgetc, getw - get character or word from stream

SYNOPSIS

       #include <stdio.h>

       int getc(stream)
       FILE *stream;

       int getchar()

       int fgetc(stream)
       FILE *stream;

       int getw(stream)
       FILE *stream;

DESCRIPTION

       Getc returns the next character from the named input stream.

       Getchar() is identical to getc(stdin).

       Fgetc behaves like getc, but is a genuine function, not a macro; it may be used to save object text.

       Getw  returns  the  next  int  (a 32-bit integer on a VAX-11) from the named input stream.  It returns the constant EOF upon end of file or
       error, but since that is a good integer value, feof and ferror(3S) should be used to check the success of getw.	Getw  assumes  no  special
       alignment in the file.

SEE ALSO

       clearerr(3S), fopen(3S), putc(3S), gets(3S), scanf(3S), fread(3S), ungetc(3S)

DIAGNOSTICS

       These  functions  return  the  integer  constant EOF at end of file, upon read error, or if an attempt is made to read a file not opened by
       fopen.  The end-of-file condition is remembered, even on a terminal, and all subsequent attempts to read will return EOF until  the  condi-
       tion is cleared with clearerr(3S).

BUGS

       Because	it  is	implemented as a macro, getc treats a stream argument with side effects incorrectly.  In particular, `getc(*f++);' doesn't
       work sensibly.
