NAME
       gets(), fgets() - get a string from a stream

SYNOPSIS
   Obsolescent Interface
DESCRIPTION
       Reads characters from the standard input stream,
		      into the array pointed to by s, until a new-line character is read or an end-of-file condition is encountered.  The new-line
		      character is discarded and the string is terminated with a null character.

       Reads characters from the
		      stream into the array pointed to by s, until n-1 characters are read, 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 character.

   Obsolescent Interface
       gets a string from a stream.

APPLICATION USAGE
       After or is applied to a stream, the stream becomes byte-oriented (see orientation(5)).

RETURN VALUE
       Upon  successful  completion,  and  return  s.  If the stream is at end-of-file, the end-of-file indicator for the stream is set and a null
       pointer is returned.

       When the file corresponding to an open stream gets extended after the end-of-file is reached, any subsequent calls to these functions  will
       succeed	and the end-of-file indicator will remain set.	However, in the UNIX2003 standards environment (see standards(5)), these functions
       will return a null pointer and the end-of-file indicator will still remain set.

       If a read error occurs, the error indicator for the stream is set, is set to indicate the error, and a null pointer is returned.

       and can be used to distinguish between an error condition and an end-of-file condition.

ERRORS
       and fail if data needs to be read into the stream's buffer, and:

       The	      flag is set for the file descriptor underlying stream and the process would be delayed in the read operation.

       The file descriptor underlying
		      stream is not a valid file descriptor open for reading.

       The read operation was terminated due to the receipt of a signal,
		      and either no data was transferred or the implementation does not report partial transfer for this file.

       The process is a member of a background process
		      and is attempting to read from its controlling terminal, and either the process is ignoring or blocking the  signal  or  the
		      process group of the process is orphaned.

       Additional values can be set by the underlying function (see read(2)).

WARNINGS
       is an obsolescent interface supported only for compatibility with existing DCE applications. New multithreaded applications should use
