getc, fgetc - get a character from a logical unit
integer function getc (char)
integer function fgetc (lunit, char)
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).

getc, getchar, fgetc, getw - get character or word from stream
int getc(FILE *stream)
int fgetc(FILE *stream)
int getw(FILE *stream)
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 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 clearerr(3), fopen(3), putc(3), gets(3), scanf(3), fread(3), ungetc(3).
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(3).
Because it is implemented as a macro, getc treats a stream argument with side effects incorrectly. In particular, `getc(*f++);' doesn't
