GetCurrentDirectoryThe GetCurrentDirectory function retrieves the current directory for the current process.  DWORD GetCurrentDirectory(   DWORD nBufferLength, // size, in characters, of directory buffer   LPTSTR lpBuffer // pointer to buffer for current directory);  

创建文件是你自己把路径给出来就行了撒，如：D:\file\file.dat

程序所在的目录，就是直接"./"啊，或是直接空路径

我不想用GetModuleFileName,我还想把程序移植到linux呢.我试过 帮助文档  // crt_fopen_s.c// This program opens two files. It uses// fclose to close the first file and// _fcloseall to close all remaining files.  #include <stdio.h>FILE *stream, *stream2;int main( void ){   int numclosed;   errno_t err;   // Open for read (will fail if file "crt_fopen_s.c" does not exist)   if( (err = fopen_s( &stream, "crt_fopen_s.c", "r" )) !=0 )   printf( "The file ‘crt_fopen_s.c’ was not opened\n" );   else   printf( "The file ‘crt_fopen_s.c’ was opened\n" );   // Open for write    if( (err = fopen_s( &stream2, "data2", "w+" )) != 0 )   printf( "The file ‘data2′ was not opened\n" );   else   printf( "The file ‘data2′ was opened\n" );   // Close stream if it is not NULL    if( stream)   {   if ( fclose( stream ) )   {   printf( "The file ‘crt_fopen_s.c’ was not closed\n" );   }   }   // All other files are closed:   numclosed = _fcloseall( );   printf( "Number of files closed by _fcloseall: %u\n", numclosed );}能行,但是用到我的程序上也没有改多少   char filename[20], tmp_char; FILE *fp; scanf_s("%s",filename,20); errno_t err; //打开文件只读 if( (err = fopen_s( &fp,filename, "r" )) != 0 ) { printf(">文件%s没有找到.\n",filename); system("pause"); exit(0); } else { tmp_char=fgetc(fp); putchar(tmp_char); printf( ">文件%s已经读取.\n",filename ); system("pause"); fclose(fp); }就提示的是,没有输入错误.文件google.txt没有找到.我确实是在程序所在目录有个google.txt.为了以防万一在主文件夹下也放了个google.txt.也报同样的错.
