分析路径参数函数_splitpath

以前也写过分析程序运行路径的博文http://blog.csdn.net/qiuyeting/article/details/7305077，但今天偶然发现有更好的函数可以帮助我们分析路径参数。这个函数就是_splitpath。

函数原型：

void _splitpath(
const char *path,
char *drive,
char *dir,
char *fname,
char *ext
);
void _wsplitpath(
const wchar_t *path,
wchar_t *drive,
wchar_t *dir,
wchar_t *fname,
wchar_t *ext
);

参数含义：

path
Full path buffer. _makepath does not check that path does not
exceed _MAX_PATH.

drive
Drive letter.

dir
Directory path.

fname
File name.

ext
File name extension.

实例：

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
int main( void )
{
char path_buffer[_MAX_PATH];
char drive[_MAX_DRIVE];
char dir[_MAX_DIR];
char fname[_MAX_FNAME];
char ext[_MAX_EXT];

//获取当前运行程序的完整路径，赋值给path_buffer
strcpy(path_buffer,__argv[0]);
_splitpath( path_buffer, drive, dir, fname, ext );
// Note: _splitpath is deprecated; consider using _splitpath_s instead
printf( "Path extracted with _splitpath:\n" );
printf( "  Drive: %s\n", drive );
printf( "  Dir: %s\n", dir );
printf( "  Filename: %s\n", fname );
printf( "  Ext: %s\n", ext );

return 0;
}

运行结果：
