我要做的就是打印调用给定行的方法堆栈。我从https://stackoverflow.com/a/5699483/393087答案中获得了代码。稍微重构它以显示问题所在。
#include <windows.h>
#include <iostream>
#include <imagehlp.h>
#include <dbghelp.h>
void printStack( void ) {
HMODULE dbghelp_lib = LoadLibrary("dbghelp.dll");
if (NULL == dbghelp_lib) {
printf("dbghelp.dll failed");
}
HANDLE process = GetCurrentProcess();
if (!SymInitialize( process, NULL, TRUE )) {
printf("SymInitialize failed: %d\n", GetLastError());
abort();
} else SetLastError(0);
void * stack[100];
ULONG FramesToSkip = 0;
ULONG FramesToCapture = 32;
unsigned short frames = CaptureStackBackTrace( FramesToSkip, FramesToCapture, stack, NULL );
SYMBOL_INFO * symbol;
symbol = ( SYMBOL_INFO * )calloc( sizeof( SYMBOL_INFO ) + 256 * sizeof( char ), 1 );
symbol->MaxNameLen = 255;
symbol->SizeOfStruct = sizeof( SYMBOL_INFO );
for(unsigned int i = 0; i < frames; i++ ) {
if(!SymFromAddr( process, ( DWORD )( stack[ i ] ), 0, symbol )) {
printf("SymFromAddr failed: %d\n", GetLastError());
}
printf( "%i: %s - 0x%0X\n", frames - i - 1, symbol->Name, symbol->Address );
}
free( symbol );
}
void testfunc() {
printStack();
}
int main() {
testfunc();
}
它返回:
SymFromAddr failed: 487
3: - 0x0
SymFromAddr failed: 487
2: - 0x0
SymFromAddr failed: 487
1: - 0x0
0: RegisterWaitForInputIdle - 0x7C81702E
它编译和链接没有任何警告。
