Fatfs string comparison for fno.fname - c

Question

I have an issue regarding reading the size of a file on my SD card. The sizes of these files will vary in the application, I therefore, need to get the size of the file. If I run the below code I can see the files in my directory along with their size.
What I need to do is store the size of the DATA.CSV file as a variable.
How do I add a comparision to get the fno.fsize when the listing is "data.csv
This prints out:
00> Listing directory: /00> 0 EVENTLOG.CSV <DIR> SYSTEM~1 183600 DATA.CSV ```
void Get_data_csv_file_size()//of the data csv
{
if(Logging_UART_SD_CARD == true){NRF_LOG_INFO("\r\n Listing directory: /");}
ff_result = f_opendir(&dir, "/");
if (ff_result)
{
if(Logging_UART_SD_CARD == true){NRF_LOG_INFO("Directory listing failed!");}
}
do
{
ff_result = f_readdir(&dir, &fno);
if (ff_result != FR_OK)
{
if(Logging_UART_SD_CARD == true){NRF_LOG_INFO("Directory read failed.");}
}
if (fno.fname[0])
{
if (fno.fattrib & AM_DIR)
{
if(Logging_UART_SD_CARD == true){NRF_LOG_RAW_INFO(" <DIR> %s",(uint32_t)fno.fname);}
}
else
{
if(Logging_UART_SD_CARD == true){NRF_LOG_RAW_INFO("%9lu %s", fno.fsize, (uint32_t)fno.fname);}
if(strcmp((uint32_t)fno.fname, "data.csv")==0)//Convert both to a uint32_t
{
Size_of_file = fno.fsize;//Set the size of the file
//Does not get to here
}
}
}
}
while (fno.fname[0]);
}
Note this is programmed in C using a arm board. What operation do I need to do so I can get the file size?
I want something like:
if(fno.name == "data.csv")
{
Size_of_file = fno.fsize;//Set the size of the file
}

Just in case you determine using an implementation of stricmp() would be useful, here is one that I have used:
//case insensitive string compare
int cb_stricmp(const char *a, const char *b)
{
if(!a) return -1;
if(!b) return -1;
int ch_a = 0;
int ch_b = 0;
while ( ch_a != '\0' &&ch_a == ch_b)
{
ch_a = (unsigned char) *a++;
ch_b = (unsigned char) *b++;
ch_a = tolower(toupper(ch_a));
ch_b = tolower(toupper(ch_b));
}
return ch_a - ch_b;
}

Found a solution using snprintf neeeded to convert fno.fname to a string to compare the result.
char string_test[9] = "DATA.CSV";
char name_test[9]={0};
snprintf(name_test, sizeof(name_test),"%s",(uint32_t)fno.fname);
NRF_LOG_INFO("Result is: %s",name_test);
int result = strcmp(name_test, string_test);
if(result==0)//Convert both to a uint32_t
{
Size_of_file = fno.fsize;//Set the size of the file
NRF_LOG_INFO("Size of file using is: %9lu",Size_of_file);
}
