Hi.
I am trying to read a file that basically contains the following:
RXbytes = 98 b TXbytes = 98 b
RXbytes = 98 b TXbytes = 98 b
RXbytes = 6 Kb TXbytes = 3 Kb
RXbytes = 749 Kb TXbytes = 21 Kb
RXbytes = 955 Kb TXbytes = 25 Kb
RXbytes = 945 Kb TXbytes = 24 Kb
RXbytes = 945 Kb TXbytes = 24 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 964 Kb TXbytes = 23 Kb
RXbytes = 945 Kb TXbytes = 25 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 958 Kb TXbytes = 24 Kb
RXbytes = 950 Kb TXbytes = 24 Kb
RXbytes = 945 Kb TXbytes = 24 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 945 Kb TXbytes = 24 Kb
RXbytes = 945 Kb TXbytes = 24 Kb
RXbytes = 945 Kb TXbytes = 23 Kb
RXbytes = 152 Kb TXbytes = 4 Kb
RXbytes = 98 b TXbytes = 98 b
RXbytes = 98 b TXbytes = 98
but however the following error
*** Break *** segmentation violation

what is wrong with my fscanf?
