The Output of the program will be displayed as similar to this:
Partition 1 - FAT32
Partition 2 - FAT32
Partition 3 - FAT32
Total Partitions in Disk = 3
Starting Sector Number of Partition 1 = 63
Starting Sector Number of Partition 2 = 11277693
Starting Sector Number of Partition 3 = 25623738 |
Comments on coding:
The structure diskaddrpacket is used to read Disk Address packet format, to be used by the readabsolutesectors function.
The function All_partition_information( ) is used to find all the parameters of all partitions from the partition entry.
Although in this program, we have displayed only the File system and relative sector information of all available logical partitions in the disk, you can also print the information of other parameters of partition information by using the function All_partition_information( ) with some more printf.
The coding of the function is as follows:
/* Function to Find all logical partitions’ information
reading their partition entry */
All_partition_information( unsigned long *star_sec,
unsigned *no_par,
long *sec, char *buffer,
unsigned char *report_par )
{
unsigned long fat_check;
unsigned long *sectors_part;
static long se_p;
int temp_var1,active_offset,active_pos=0,i, extended_pos=0, partloc1;
unsigned long b_sec,se;
unsigned char active_par;
long relative_sec;
long no_sectors;
if(*sec==0 || *sec==1)
se_p=0;
do{
se=*sec;
/* Read absolute sector specified by *sec */
readabsolutesectors(drive_num,*sec,1,buffer);
