FGETC(3)                            Linux Programmer's Manual                            FGETC(3)

       fgetc, fgets, getc, getchar, ungetc - input of characters and strings

       #include <stdio.h>

       int fgetc(FILE *stream);

       char *fgets(char *s, int size, FILE *stream);

       int getc(FILE *stream);

       int getchar(void);

       int ungetc(int c, FILE *stream);

       fgetc() reads the next character from stream and returns it as an unsigned char cast to an
       int, or EOF on end of file or error.

       getc() is equivalent to fgetc() except that it may be implemented as a macro which  evalu‐
       ates stream more than once.

       getchar() is equivalent to getc(stdin).

       fgets()  reads  in  at most one less than size characters from stream and stores them into
       the buffer pointed to by s.  Reading stops after an EOF or a newline.   If  a  newline  is
       read,  it  is  stored into the buffer.  A terminating null byte ('\0') is stored after the
       last character in the buffer.

       ungetc() pushes c back to stream, cast to unsigned char, where it is available for  subse‐
       quent read operations.  Pushed-back characters will be returned in reverse order; only one
       pushback is guaranteed.

       Calls to the functions described here can be mixed with each other and with calls to other
       input functions from the stdio library for the same input stream.

       For nonlocking counterparts, see unlocked_stdio(3).

       fgetc(), getc() and getchar() return the character read as an unsigned char cast to an int
       or EOF on end of file or error.

       fgets() returns s on success, and NULL on error or when end of file occurs while no  char‐
       acters have been read.

       ungetc() returns c on success, or EOF on error.

       It  is not advisable to mix calls to input functions from the stdio library with low-level
       calls to read(2) for the file descriptor associated with the  input  stream;  the  results
       will be undefined and very probably not what you want.
