Hello again, Thanks to Salem for the previous help, but I still can't seem to work this out... I apologize to all. Before I had asked to read many different struct-like records, dynamically allocate memory for each and then print them to stdout, but it would seem something for linked-lists and I'd prefer to avoid this. So it would be simpler ... |
Hi guys, Im a Perl programmer in the origin, finding it a bit hard to write regex in 'c'. what I have is a hex file that I wish to read and arrange in an array of INTEL_HEX_RECORD: example: the hex file looks like this: file.hex: :03000300020ECD1D :100ECD00C0E0C0D075D000C007C289D203AF5CEFBF :100EDD0054FEF55CAF5CEF54EFF55CAF5CEF1313B4 :100EED00543F20E007AF5CEF4408F55CD007D0D04D :030EFD00D0E03210 :030023000211784F :10117800C0E0C0D075D00830991BC299E54E6551C2 and more... and the structure of the array ... |

In the first place, your description leaves some impression that you didn't allow for nul terminators on the strings. This would cause such an effect. In the second place, your structure might have padding in it that leaves 'holes' of junk. If you write it FROM the structure to the file, then you can read it TO the structure directly assuming ... |

Then, I'm ... |
Hi Everyone, I am having a bit of a problem reading from a file using a struct and I was hoping you can help me out. The compiler states that the the statements, "data->title_ptr" and "data->genre_ptr" are not lvalues, but occur in a context that require one. This is strange because I do the same format for the dbid and rating ... |
