NAME

       getc, fgetc - get a character from a logical unit

SYNOPSIS

       integer function getc (char)
       character char

       integer function fgetc (lunit, char)
       character char

DESCRIPTION

       These routines return the next character from a file associated with a fortran logical unit, bypassing normal fortran I/O.  Getc reads from
       logical unit 5, normally connected to the control terminal input.

       The value of each function is a system status code. Zero indicates no error occurred on the read; -1 indicates end of file was detected.  A
       positive value will be either a UNIX system error code or an f77 I/O error code. See perror(3F).

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 word 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(3) should be used to check the success of getw.  Getw assumes no special alignment in the file.

SEE ALSO

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

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
       fopen.

BUGS

       The end-of-file return from getchar is incompatible with that in UNIX editions 1-6.

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