Hello,
I am using WP7608 module. In that, trying to write some data.
So, i created directory in /home/root - folder name “TR_VT_ADV” and for writing i am using below mentioned API,
///////////////////////////////////////////////
#define wt_fil “/home/root/TR_VT_ADV/configFile.txt” // path
char name[15] = "Hello World ";
COMPONENT_INIT
{
system("/bin/mkdir /home/root/TR_VT_ADV");
char importStr[15]={0};
sprintf(importStr,"%s",name);
if(fileStore->fWriteFile(wt_fil, importStr, strlen(importStr)) == 1)
LE_INFO("\n Import hour time saved to file %s",importStr);
else
LE_INFO("\n Import hour time save failed");
delete fileStore;
}
///////////////////////////////////////////
int FileStorageProcess::fWriteFile(const char* fileNamePath, const char* writeString, unsigned int StringByteLength)
{
int ret_tp = -1;
LE_INFO("\n into fWriteFile()");
int fileHandler = 0;
LE_INFO("\n File path");
LE_INFO(fileNamePath);
LE_INFO("\n");
fileHandler = le_atomFile_Create(fileNamePath,LE_FLOCK_READ_AND_WRITE ,LE_FLOCK_OPEN_IF_EXIST,O_RDWR|O_CREAT);
if(LE_DUPLICATE == fileHandler)
{
LE_INFO("\n file descripter duplicate");
}
else if(LE_FAULT == fileHandler)
{
LE_INFO("\n file descripter fault");
}
else if(fileHandler > 0)
{
size_t len = StringByteLength;
size_t res = write(fileHandler,writeString,len);
if(res > 0)
{
LE_INFO(" write data to file %d ", res );
ret_tp = 1;
}
else
{
LE_INFO(" write data failed ");
}
if(fileHandler != 0){
le_result_t result;
result = le_atomFile_Close(fileHandler);
if(result == LE_OK)
{
LE_INFO("file desc closed file ");
fileHandler = 0;
}
else
{
LE_INFO("file descr closing failed");
fileHandler = 0;
}
}
}
else
{
LE_INFO("File descriptor not created");
}
return ret_tp;
}
