1eb0f442c7 Reimplement more efficiently, using a single forward scan (like strrchr(3)) 
instead of scanning forwards to find the end of the string then scanning
backwards to find the character.

4bf546e192 Replace this wcsncpy() implementation with one based on strncpy.c to fix 
two major bugs:
- off-by-one overflow when the length of the source string exceeds or
  equals the destination buffer size.
- old version was not padding the destination buffer with null wide chars

bc0ad8e7a1 - Let their manual pages show the reader that the bzero(3) and 
bcopy(3) functions are prototyped in <strings.h> and not in
   <string.h> anymore.
 - Add a sentence about that to the respective HISTORY sections.
In the C source files:
 - Include <string.h> or <strings.h> depending on what function
   is to be compiled.
 - Use ANSI-C function definitions.
 2002-09-01 21:53:46 +00:00

2f4772b37f Add the 'restrict' type qualifier to the function prototype 
of the swab(3) function in its manual page to match the
standardization by POSIX.1-2001.

9abf5797a0 - Update the manual page of bcmp(3) by replacing 
.In string.h
   with
     .In strings.h
   and adding a sentence to the HISTORY section.
 - Use an ANSI-C function definition.
 - Include <strings.h> instead of <string.h>.
 - Apply style(9): Put a space after return keywords.
 2002-08-30 21:07:40 +00:00
Robert Drehmel
c9ab23eea5 - Convert the function definition to declare its arguments 
in the ANSI-C format.
 - Change the code a bit to hopefully save some cycles.
   I.e. (simplified) change

     a = b + 1;
     while (--b & 0x7)
	/* ... */
   to
     a = b;
     for (; b & 0x7; b--)
	/* ... */
   and
     while (--a >= 0)
	/* ... */
   to
     for (; a > 0; a--)
	/* ... */
 - Equip two function arguments of swab() with the 'restrict'
   type qualifier in form of the '__restrict' macro.  This is
   specified by POSIX.1-2001.
 2002-08-30 20:33:05 +00:00
Robert Drehmel
425289a9db - Update the manual pages of index() and rindex() to show 
<strings.h> as the associated header file.
   The prototypes have been moved there from <string.h> because
   POSIX.1-2001 said so.
 - Conditionally include either <strings.h> or <string.h> based
   on whether the [r]index() or str[r]chr() functions are
   compiled, respectively.
 - Style(9) tells us to
    - put a space after the return keyword
    - to check for a NUL character without using the ! operator.
    - use NULL instead of (type *)NULL where the compiler knows
      the type.
   Apply these rules.
 - Rather use ANSI-C function definitions than K&R ones.
 - For index(3), correct second function argument's type; it was
   declared to be a `const char' before and is now an `int'.

554331bbb9 - Update the manual page to show that the associated header file 
is <strings.h> and not <string.h> anymore.
 - Tell the reader about this change in the HISTORY section.
 - Switch to use an ANSI-C function definition.
 - Include <strings.h> instead of <string.h> in the source file.
 2002-08-30 19:08:53 +00:00
Robert Drehmel
c271a3613c - Update strcasecmp(3)/strncasecmp(3) to reflect the fact that 
the prototypes for both functions are now in the <strings.h>
   header, as required by IEEE Std 1003.1-2001.
 - Add one sentence about that in the HISTORY section.
 - Include <strings.h> in the source file to have the prototypes
   in scope when the _ANSI_SOURCE macro is defined.
