strrev(), _strrev(), _fstrrev()

reverse a string

Synopsis:

#include <string.h>

char *strrev( char *s1 );
char *_strrev( char *s1 );
char __far *_fstrrev( char __far *s1 );

Description:

The strrev() function replaces the string s1 with a string whose characters are in the reverse order.

The _strrev() function is identical to strrev(). Use _strrev() for ANSI/ISO naming conventions.

The _fstrrev() function is a data-model-independent form of the strrev() function. It accepts far pointer arguments, and returns a far pointer. It is most useful in mixed memory model applications.

Returns:

The address of the original string s1.

Examples:

#include <stdio.h>
#include <string.h>

char source[] = { "A sample STRING" };

void main()
  {
    printf( "%s\n", source );
    printf( "%s\n", strrev( source ) );
    printf( "%s\n", strrev( source ) );
  }

produces the output:

A sample STRING
GNIRTS elpmas A
A sample STRING

Classification:

_strrev() conforms to ANSI/ISO naming conventions.
