In project development, it is often necessary to traverse some resource files in a certain folder. In order to avoid reinventing the wheel, I just recorded it here.
Implementation ideas
1. Give a folder name
2. Obtain the file handle
3. Filter out .
the sum ..
(upper level and current directory)
4. Identify folders, files, etc. by obtaining the attributes __finddata64_t
of the structureattrib

// File attribute constants for the _findfirst() family of functions
#define _A_NORMAL 0x00 // Normal file - No read/write restrictions
#define _A_RDONLY 0x01 // Read only file
#define _A_HIDDEN 0x02 // Hidden file
#define _A_SYSTEM 0x04 // System file
#define _A_SUBDIR 0x10 // Subdirectory
#define _A_ARCH 0x20 // Archive file
source code
When your development environment is 32-bit, you need to change the __finddata64_t
, _findfirst64
, _findnext64
three to _finddata32_t
, _findfirst
, _findnext
.
std::string path = "./tset/"+ '*';
__finddata64_t fileInfo;
intptr_t hFile = _findfirst64(path.c_str(), &fileInfo);
if(-1 != hFile)
{
do
{
if(_A_SUBDIR == fileInfo.attrib && 0 != strcmp(fileInfo.name, ".") && 0 != strcmp(fileInfo.name, ".."))
{
qDebug() << QString::fromStdString(fileInfo.name);
}
}while(0 == _findnext64(hFile, &fileInfo));
}
