CDT+cygwin C++文件夹操作

环境：eclipse  + CDT +cygwin

前提：可以运行一个hello word的C project

功能：判断指定文件夹是否存在；创建指定多层文件夹。

预期跨平台代码：

 

#define _LINUX   1
//#define _WIN32   1

#ifdef _WIN32
#include <direct.h>
#include <io.h>
#elif _LINUX
#include <stdarg.h>
#include <sys/stat.h>
#endif

#ifdef _WIN32
#define ACCESS _access
#define MKDIR(a) _mkdir((a))
#elif _LINUX
#define ACCESS access
#define MKDIR(a) mkdir((a),0755)
#endif
#include  <io.h>
#include  <stdio.h>
#include  <stdlib.h>
#include <string.h>


int is_directory(const char *path) {
	/* Check for existence */
	if ((ACCESS(path, 0)) != -1) {
		/*printf( "File  exists \n" );
		 if( (access( path, 1 )) != -1 )
		 printf( "File  has read permission \n" );
		 if( (access( path, 2 )) != -1 )
		 printf( "File  has write permission \n" );*/
		return 1;
	} else {
		//printf( "File  not exists \n" );
		return 0;
	}
}
int create_directory(const char *path) {
	if (is_directory(path)) {
		printf("Directory existed\n");
		return 0;
	}

	char tmpPath[300];
	const char* pCur = path;

	memset(tmpPath, 0, sizeof(tmpPath));
	int pos = 0;
	while (*pCur++ != '\0') {
		tmpPath[pos++] = *(pCur - 1);
		if (*pCur == '/' || *pCur == '\0') {
			if (!is_directory(tmpPath) && strlen(tmpPath) > 0) {
				if (MKDIR( tmpPath ) == 0) {
					printf(tmpPath);
					printf("\n");
					printf("Success creating directory \n");
				} else {
					printf(tmpPath);
					printf("\n");
					printf("Error creating directory \n");
					return 0;
				}
			}
		}
	}
	//printf("Success creating directory all\n");
	return 1;

}

int main(void) {
	if (is_directory("/cygdrive/c/a/a")) {
		printf("dir exists \n");
	} else {
		printf("dir not exists \n");
		create_directory("/cygdrive/c/a/a");
	}
}

 

 

真正linux环境有待测试。
