windows下wchar_t* 转char*

这个在windows下很常见,常用，留个档。

一般用这个函数：

size_t wcstombs(   char *mbstr,   const wchar_t *wcstr,   size_t count );

mbstr

The address of a sequence of multibyte characters.

wcstr

The address of a sequence of wide characters.

count

The maximum number of bytes that can be stored in the multibyte output string.

locale

The locale to use.

 

下面是我写的一个测试,是根据项目改过来的：

 1 #include <windows.h> 2 #include <string.h> 3 #include <stdio.h> 4 #include <stdlib.h> 5 #include <boost/filesystem.hpp> 6  7 namespace bfs = boost::filesystem; 8  9 10 bool get_path(char *file_name,size_t size){11 12 13 char ownPth[MAX_PATH];14 15 HMODULE hModule = GetModuleHandle(NULL);    // Will contain exe path，When passing NULL to GetModuleHandle, it returns handle of exe itself16 if (hModule != NULL)17 {18 GetModuleFileNameA(hModule,ownPth, MAX_PATH);    // 19 }20 else21 ownPth[0]=0;22 23 bfs::path iic_file(ownPth);24 iic_file = iic_file.parent_path() / "dlp_usb.iic" ; //For releaseing25 26 if( !bfs::is_regular_file(iic_file))27 {28 printf("\r\nError,open 68013 iic file fail\r\n");29 return false ;30 }31 32 33 wcstombs(file_name,iic_file.c_str(),size);34 35 //memcpy(file_name,iic_file.c_str(),byte_count);36 37 return true;38 39 }40 41 int main(){42 43 char iic_file[512];44 45 if(get_path( iic_file,512)){46 47 printf("TRUE\n");48 }49 50 return 0;51 }
