An error in the book "data structures and algorithms under multiple tasks"

The following are the current errors. I believe there are still many problems that have not been found in the book. Please promptly raise new errors and I will fix them as soon as possible.

1. P52 page 15th Line Original"Returns the number 0 in the HOOK array."Changed to"Returns the serial number in the HOOK array when the result is successful."

2. Line 3 on page 53Returns the number 0 in the HOOK array."Changed to"Returns the serial number in the HOOK array when the result is successful."

3. The Xcopy () function code on pages P164 and P165 is incorrect. The correct code is as follows:

/** Copy all files in one directory and subdirectory to another directory

@ Param char * pszSrcDir-source directory to be copied
@ Param char * pszTargeDir-target directory
@ Param BOOL bOverWrite-overwrite flag; FALSE indicates Overwrite
@ Return void-None
*/
Void Xcopy (char * pszSrcDir, char * pszTargeDir, BOOL bOverWrite)
{
Char lBaseSearch [MAX_PATH];
HANDLE lhFile;
WIN32_FIND_DATA lfData;

Sprintf (lBaseSearch, "% s // *. *", pszSrcDir );
LhFile = FindFirstFile (lBaseSearch, & lfData );
If (lhFile = INVALID_HANDLE_VALUE ){
Return;
}
Do {
CreateDirectory (pszTargeDir, NULL );
If (! Strcmp (lfData. cFileName, ".") |
! Strcmp (lfData. cFileName ,"..")){
/* Skip. and... not processed */
Continue;
}
If (lfData. dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY ){
/* Directory */
Char szBaseDir [MAX_PATH];
Char szTargeDir [MAX_PATH];

Sprintf (szBaseDir, "% s // % s", pszSrcDir, lfData. cFileName );
Sprintf (szTargeDir, "% s // % s", pszTargeDir, lfData. cFileName );
Xcopy (szBaseDir, szTargeDir, bOverWrite );
}
Else {
/* Common File */
Char szBaseDir [MAX_PATH];
Char szTargeDir [MAX_PATH];

Sprintf (szBaseDir, "% s // % s", pszSrcDir, lfData. cFileName );
Sprintf (szTargeDir, "% s // % s", pszTargeDir, lfData. cFileName );

CopyFile (szBaseDir, szTargeDir, bOverWrite );
}
} While (FindNextFile (lhFile, & lfData ));
FindClose (lhFile );
}

4. The original Article"Where will the sending operation be blocked?" After modification,The sending operation is blocked."

5. P203 page 22nd ~ The 29 lines are as follows:

If (pDelNode = pANode-> pLeft)
{
PANode-> nMagic-= 1;
}
Else
{
Panode-> nmagic + = 1;
}
You need to move this code between lines 9th and 10th on the P203 page, and the modified 9th ~ The 21 lines of code are:

Pnode-> pdata = pdelnode-> pdata;
If (pdelnode = panode-> pleft)
{
Panode-> nmagic-= 1;
}
Else
{
Panode-> nmagic + = 1;
}
If (pDelNode! = PNode-> pLeft)
{
PANode-> pRight = pDelNode-> pLeft;
}
