Reading and writing files

[doublebond]

Hi all,

I have a problem with my code. Please help me.

I am trying to create multiple files based on the input file and read its respective data only.

Thread_id: 1
Data_block_size: 64
Request_commmand_type: ReadReq
Packet_block_Address: 8184256
PC_value: 4831838656
Tick_of_the_data: 14000
Packet_transfers_through_Bus_name: system.toL2Bus
Is_Instruction: 0
Is_Data: 0
Data_Read: 0
Data_Write: 1
Bits_on_packet: 010101010001011110000000001111111111

The above is a block of information in my input file. I am trying to create a file named on Data_block_size, Packet_transfers_through_Bus_name, and Is_Instruction. And write the Bits_on_packet in to the file.

The problem is I am unable to write the correct data into the correct file.

Please find the code below.

Cheers,

It seems the problem is fscanf() -- it will only read up until the first white space( spaces, tabs, ets ). If you need the entire line then use fgets() to read the line and then parse it -- call strchr() to find the colon then extract the rest.
