Excuse me, what's the problem with the following code?

CodePudding user response:

STR is only a memory, multiple calls will be chaos

CodePudding user response:

Is it possible is the length of strSource may outweigh the MAX_STR_LEN, leading to an array

CodePudding user response:

Possible, so you have a code problem

 
Char * _strdup (const char * strSource) 
{
If (strSource==NULL) 
return NULL; 
Int len=strlen (strSource); 
Char * result=(char *) malloc (sizeof (char) * (len + 1)); 
Strcpy (result, strSource); 
Result [len]='\ 0'; 
return result; 
} 

CodePudding user response:

1) suspected of crossing the line, this can't avoid an array,
2) multithreaded operations, this function is not atomic operations, multi-threaded operation data content may be chaotic;
