c++ - ReadConsoleOutputCharacter gives ERROR_NOT_ENOUGH_MEMORY when requesting more than 0xCFE1 characters, is there a way around that? -

-

the code:

#include <windows.h> #include <stdio.h> int main() {   system("mode 128");   int range = 0xcfe2;   char* buf = new char[range+1];   dword dwchars;   if (!readconsoleoutputcharacter(     getstdhandle(std_output_handle),     buf,  // buffer store symbols     range,     // read len chars     {0,0},    // read row=8, column=6     &dwchars // how many symbols stored   )) {     printf("getlasterror: %lu\n", getlasterror());   }   system("pause");   return 0; }

console screen buffers cannot larger 64k. each character in buffer requires 2 bytes, 1 character code , color attributes. therefore never makes sense try read more 32k chars readconsoleoutputcharacter().

you don't have real problem.
