linux 创建多级目录

在linux在如果创建目录的中间路径不存在，则会创建失败，下面给一份创建多级目录的代码。

递归：

#include "stdio.h"
#include "string.h"
#include <sys/stat.h> 
#include <unistd.h> 

#define PATH	"ggyy1/ggyy2/ggyy3/ggyy4/ggyy5"
#define PATH1	"ggyy1/gg yy2/ggyy3/ggyy4/ggyy5/ggyy1/ggyy2/ggyy3/ggyy4/ggyy5"


#ifndef FALSE
  #define FALSE 0
#endif
#ifndef TRUE
  #define TRUE  1
#endif
typedef unsigned char ubyte;
typedef ubyte bool_t;


bool_t Logm_IsFileExist(const char *path);
int Logm_CheckAndCreateDir(const char* path);


int main()
{
  printf("ggyy\n");


  if(0 == Logm_CheckAndCreateDir(PATH1))
  {
    printf("create success\n");  
  }


  return 0;
}


bool_t Logm_IsFileExist(const char *path)
{
  return access(path, F_OK) == 0 ? TRUE : FALSE;
}


int Logm_CheckAndCreateDir(const char* path)
{
  char path_tmp[1024];
  char upper_path_temp[1024];
  char* p = NULL;


  memset(path_tmp, 0, sizeof(path_tmp));
  memset(upper_path_temp, 0, sizeof(upper_path_temp));


  /*check param*/
  if(NULL==path || strlen(path)<=0 || strlen(path)>=1024)
  {
      return -1;
  }


  strncpy(path_tmp, path, sizeof(path_tmp)-1);


  /*dir no exist*/
  if(!Logm_IsFileExist(path_tmp))
  {
    /*get upper dir*/
    strncpy(upper_path_temp, path_tmp, sizeof(upper_path_temp)-1);
    p = strrchr(upper_path_temp, '/');


    /*if upper dir exist*/
    if(NULL != p)
    {
      p[0] = 0;
      /*check and create upper dir*/
      if(0 != Logm_CheckAndCreateDir(upper_path_temp))
      {
        return -1;
      }
    }


    /*create current dir*/
    if (mkdir(path_tmp, ((S_IRWXU |S_IRGRP | S_IXGRP | S_IROTH | S_IXOTH))) == 0)

    else
