hi,
i have written this strcat but sometime it is giving problem, while
handeling some strings containing
binary and if string containing zero ,
funtion which takes string 1 and its length string2 and its length as
arguments

please tell the correction ,

here iam using
typedef char SINT8;
typedef unsigned char UINT8;
typedef short SINT16;
typedef unsigned short UINT16;
typedef int SINT32;
typedef unsigned int UINT32;
typedef long long UINT64;

UINT8 *
Stringcat (UINT8 *str1
, UINT32 str1len
, UINT8 *str2
, UINT32 str2len )
{
UINT8 *str3, *temp;
temp = str3 = (char *) calloc (( str1len + str2len) + 1) ,1 );
while ( ( *str3++ = *str1++) );
str3--;
while ( ( *str3++ = *str2++ ) );
return temp;
}
