Thank you for completely answering the homework template.

Please use code tags, like [code] stuff [/code] to post code. This preserves indentation in your code, makes it clear where code begins and ends, and prevents random things from turning into smilies.

I see a typo in some of your code. dimy vs dimY. Except for that, your 'assign by value' code actually worked -- so I suspect there's something else wrong in code you didn't post. Please post your complete program.

Also, the only time you can assign whole blocks of memory with { ... } is when the variable is being declared -- so you could do this:

Code:

typedef struct _blocks {
    int X, Y ,dimX, dimY;
} str_blocks;

int main()
{
        str_blocks blocks[3]={
                {50, 50, 150, 20},
                {200, 50, 150, 20},
                {300, 150, 150, 20},
        };

}

g3tolj(1)						       mgetty+sendfax manual							 g3tolj(1)

NAME

       g3tolj - converts a Group 3 fax file into a printable HP-PCL file

SYNOPSIS

       g3tolj  [-kludge]  [-reversebits]  [-scale N]  [-aspect N]  [-resolution 75|100|150|300]  [-compress 0|1|2]  [-pagelength N] [-duplength N]
       [g3file]

DESCRIPTION

       Reads a Group 3 fax file (raw or digifax) as input. If no filename is given, stdin is used.  Produces a printable HP-PCL file as output.

OPTIONS

       -kludge
	      Tells g3tolj to skip the first lines for synchronisation.

       -reversebits
	      Tells g3tolj to interpret bits least-significant first, instead of the default most-significant first.  Apparently some  fax  modems
	      do it one way and others do it the other way.  If you get a whole bunch of "invalid code" messages, try using this flag.

       -scale N
	      Scale the output to match the printer resolution and paper size, the default of 1.40 will do in most cases.

       -aspect N
	      Scale  the  output to match the printer resolution and paper size, the default of 1.0 will do for high resolution faxes, 2.0 will do
	      for low resolution faxes.

       -resolution 75|100|150|300
	      Selects print resolution. The default is 300.

       -compress 0|1|2
	      Selects compression method for the print output. 0 = none, 1 = rll, 2 = tiff.  The default is 0.

       -pagelength N
	      Defines the pagelength in inches, the default is 10.95. After this length a pagebreak is generated and the last part of the previous
	      page is duplicated on the next page

       -duplength N
	      Defines the length in inches that will be duplicated after a pagebreak, The default is 0.7.

REFERENCES

       The standard for Group 3 fax is defined in CCITT Recommendation T.4.
