本文介绍了删除文件夹和所有文件/子目录的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
如何在C ++中删除包含所有文件/子目录(递归删除)的文件夹?
解决方案
/ p>
system(rm -rf / path / to / directory)
pre>
也许更多的是你正在寻找,但unix特定:
/ *实现系统(rm -rf)* /
#include< stdlib.h>
#include< unistd.h>
#include< stdio.h>
#include< sys / syslimits.h>
#include< ftw.h>
/ *根据需要在路径上调用unlink或rmdir。 * /
int
rm(const char * path,const struct stat * s,int flag,struct FTW * f)
{
int status;
int(* rm_func)(const char *);
switch(flag){
默认值:rm_func = unlink;打破;
case FTW_DP:rm_func = rmdir;
}
if(status = rm_func(path),status!= 0)
perror(path);
else
puts(path);
return status;
}
int
main(int argc,char ** argv)
{
while(* ++ argv){
if(nftw(* argv,rm,OPEN_MAX,FTW_DEPTH)){
perror(* argv);
return EXIT_FAILURE;
}
}
return EXIT_SUCCESS;
}
How can I delete a folder with all it's files/subdirectories (recursive deletion) in C++?
解决方案Seriously:
system( "rm -rf /path/to/directory" )
Perhaps more what you're looking for, but unix specific:
/* Implement system( "rm -rf" ) */ #include <stdlib.h> #include <unistd.h> #include <stdio.h> #include <sys/syslimits.h> #include <ftw.h> /* Call unlink or rmdir on the path, as appropriate. */ int rm( const char *path, const struct stat *s, int flag, struct FTW *f ) { int status; int (*rm_func)( const char * ); switch( flag ) { default: rm_func = unlink; break; case FTW_DP: rm_func = rmdir; } if( status = rm_func( path ), status != 0 ) perror( path ); else puts( path ); return status; } int main( int argc, char **argv ) { while( *++argv ) { if( nftw( *argv, rm, OPEN_MAX, FTW_DEPTH )) { perror( *argv ); return EXIT_FAILURE; } } return EXIT_SUCCESS; }
