-The most efficient and secure way to use a `CString` object in called functions is to pass a `CString` object to the function. Despite the name, a `CString` object doesn't store a string internally as a C-style string that has a `NULL` terminator. Instead, a `CString` object keeps careful track of the number of characters it has. Having `CString` provide a `LPCTSTR` pointer to a `NULL` terminated string is a small amount of work that can become significant if your code has to do it constantly. The result is temporary because any change to the `CString` contents invalidates old copies of the `LPCTSTR` pointer.

The result is temporary because any change to the `CString` contents invalidates old copies of the `LPCTSTR` pointer.
 
-It does make sense in some cases to provide a C-style string. For example, there can be a situation where a called function is written in C and doesn't support objects. In this case, coerce the `CString` parameter to `LPCTSTR`, and the function will get a C-style `NULL` terminated string. You can also go the other direction and create a `CString` object by using the `CString` constructor that accepts a C-style string parameter.

However, `RegFlushKey` uses many system resources and should be called only when absolutely necessary.

 The argument pointers can be passed as separate parameters (in `_execl`, `_execle`, `_execlp`, and `_execlpe`) or as an array of pointers (in `_execv`, `_execve`, `_execvp`, and `_execvpe`). At least one parameter, `arg0`, must be passed to the new process; this parameter is `argv[0]` of the new process. Usually, this parameter is a copy of `cmdname`. (A different value doesn't produce an error.)
 
-The `_execl`, `_execle`, `_execlp`, and `_execlpe` calls are typically used when the number of parameters is known in advance. The parameter `arg0` is usually a pointer to `cmdname`. The parameters `arg1` through `argn` point to the character strings forming the new parameter list. A `NULL` pointer must follow `argn` to mark the end of the parameter list.

 The `_execv`, `_execve`, `_execvp`, and `_execvpe` calls are useful when the number of parameters to the new process is variable. Pointers to the parameters are passed as an array, `argv`. The parameter `argv[0]` is usually a pointer to `cmdname`. The parameters `argv[1]` through `argv[n]` point to the character strings forming the new parameter list. The parameter `argv[n+1]` must be a **`NULL`** pointer to mark the end of the parameter list.
 
-Files that are open when an `_exec` call is made remain open in the new process. In `_execl`, `_execlp`, `_execv`, and `_execvp` calls, the new process inherits the environment of the calling process. `_execle`, `_execlpe`, `_execve`, and `_execvpe` calls alter the environment for the new process by passing a list of environment settings through the `envp` parameter. `envp` is an array of character pointers, each element of which (except for the final element) points to a `NULL` terminated string defining an environment variable. Such a string usually has the form `NAME=value` where `NAME` is the name of an environment variable and `value` is the string value to which that variable is set. (Note that `value` isn't enclosed in double quotation marks.) The final element of the `envp` array should be **`NULL`**. When `envp` itself is **`NULL`**, the new process inherits the environment settings of the calling process.
