gets, fgets - get a string from a stream


     #include <stdio.h>

     char *gets(char *s);

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


     The gets() function reads  bytes  from  the  standard  input
     stream  (see  intro(3)), stdin, into the array pointed to by
     s, until a newline character is read or an end-of-file  con-
     dition  is  encountered.  The newline character is discarded
     and the string is terminated with a null byte.

     If the length of an  input  line  exceeds  the  size  of  s,
     indeterminate  behavior  may  result. For this reason, it is
     strongly recommended that gets()  be  avoided  in  favor  of

     The fgets() function reads bytes from the  stream  into  the
     array  pointed  to by s, until n-1 bytes are read, or a new-
     line character is read and transferred to s, or  an  end-of-
     file condition is encountered. The string is then terminated
     with a null byte.

     The fgets() function may mark the st_atime field of the file
     associated  with  stream for update. The st_atime field will
     be marked for update by the first  successful  execution  of
     fgetc(3C),   fgets(),   fgetwc(3C),  fgetws(3C),  fread(3C),
     fscanf(3C),  getc(3C),  getchar(3C),  gets(),  or  scanf(3C)
     using  stream that returns data not supplied by a prior call
     to ungetc(3C) or ungetwc(3C).


     If end-of-file is encountered and no bytes have  been  read,
     no  bytes  are  transferred  to  s  and  a   null pointer is
     returned. If a read error occurs,  such  as  trying  to  use
     these functions on a file that has not been opened for read-
     ing, a null pointer is returned and the error indicator  for
     the  stream  is  set. If end-of-file is encountered, the EOF
     indicator for the stream is set.  Otherwise s is returned.


     Refer to fgetc(3C).
