C++ (Cpp) CSTRING::GetBuffer Examples

Programming Language: C++ (Cpp)

Class/Type: CSTRING

Method/Function: GetBuffer

Examples at hotexamples.com: 1

The CString GetBuffer function in C++ returns a pointer to a buffer that can be used for reading or writing the contents of the string. The buffer must be released using the ReleaseBuffer function.

Example 1:

CString str = "Hello World!";
TCHAR* buffer = str.GetBuffer(str.GetLength());
_tcscpy_s(buffer, str.GetLength(), _T("Goodbye World!"));
str.ReleaseBuffer();

This code creates a CString object with the value "Hello World!", gets a pointer to a buffer with enough space to hold the string, modifies the contents of the buffer to say "Goodbye World!", and then releases the buffer back to the object.

Example 2:

CString str = "Lorem ipsum dolor sit amet";
char* buffer = (char*) str.GetBuffer(str.GetLength() + 1);
str.ReleaseBuffer();
std::cout << buffer;

This code creates a CString object with the value "Lorem ipsum dolor sit amet". It then gets a pointer to a buffer with enough space to hold the string plus one extra byte (to store the null terminator). It then releases the buffer and prints the contents of the buffer to the console. This function is part of the MFC (Microsoft Foundation Class) library.
