FGETS(3P)						     POSIX Programmer's Manual							 FGETS(3P)

PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       fgets - get a string from a stream

SYNOPSIS

       #include <stdio.h>

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

DESCRIPTION

       The fgets() function shall read bytes from stream into the array pointed to by s, until n-1 bytes are read, or  a  <newline>  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 shall be marked for
       update by the first successful execution of fgetc(), fgets(), fgetwc(), fgetws(), fread(), fscanf(), getc(), getchar(), gets(), or  scanf()
       using stream that returns data not supplied by a prior call to ungetc() or ungetwc().

RETURN VALUE

       Upon  successful completion, fgets() shall return s. If the stream is at end-of-file, the end-of-file indicator for the stream shall be set
       and fgets() shall return a null pointer.  If a read error occurs, the error indicator for the stream shall be set, fgets() shall  return  a
       null pointer,  and shall set errno to indicate the error.

ERRORS

       Refer to fgetc().

       The following sections are informative.

EXAMPLES

   Reading Input
       The following example uses fgets() to read each line of input.  {LINE_MAX}, which defines the maximum size of the input line, is defined in
       the <limits.h> header.

	      #include <stdio.h>
	      ...
	      char line[LINE_MAX];
	      ...
	      while (fgets(line, LINE_MAX, fp) != NULL) {
	      ...
	      }
	      ...

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
