22: .SH NAME
23: gets - get a line from stdin
24: .SH SYNOPSIS
25: .nf
26: .ft B
27: #include <stdio.h>
28:
29: char *gets(s)
30: char *s;
31: .ft R
32: .SH DESCRIPTION
33: .ft B
34: This interface is obsoleted by fgets(3).
35: As it makes no effort to avoid overwriting its buffer,
36: it's a clear security problem.
37: .br
38: It is available from the compatibility library, libcompat.
39: .ft R
40: .PP
41: The
42: .I gets
43: function reads characters from the input stream pointed to by
44: .IR stdin ,
45: into the array pointed to by
46: .IR s ,
47: until end-of-file is encountered or a new-line character is read.
48: Any newline character is discarded, and a null character is written
49: immediately after the last character read into the array.
50: .PP
51: The
52: .I gets
53: function returns
54: .I s
55: if successful.
56: If end-of-file is encountered and no characters have been read into
57: the array, the contents of the array remain unchanged and a null
58: pointer is returned.
59: If a read error occurrs during the operation, the array contents
60: are indeterminate and a null pointer is returned.
61: .SH "SEE ALSO"
62: getc(3), ferror(3) fread(3), scanf(3)
63: .SH STANDARDS
64: The
65: .I gets
66: function is ANSI C compatible.
