I already posted a thread and 2 answers did not read the data like that. ...
That's because your problem statement is quite vague. A "read" operation does not "have" a format, which is why "read" cannot "be" in any format.

Your input data in a file or from a pipe "has" or "is in" some particular format. So, I'll assume that this -

Code:
Chr18:4000-4010
Chr20:393939-400303
Chr30:38838-30020

is the format of your input data. Again, I'll assume that this data is in a file, as opposed to a pipe stream.

In the shell, you'd read a file like so -

Code:
$
$ # display the content of the file. My file is called "f32", yours may be different.
$ cat f32
Chr18:4000-4010
Chr20:393939-400303
Chr30:38838-30020
$
$ # read data from input file "f32"
$ while read LINE; do   echo "Oh my! I've now read this line => $LINE"; done < f32
Oh my! I've now read this line => Chr18:4000-4010
Oh my! I've now read this line => Chr20:393939-400303
Oh my! I've now read this line => Chr30:38838-30020
$
$

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *extract_font_range(FONT *f, int begin, int end) DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example: FONT *myfont; FONT *capitals; FONT *fontcopy; ... /* Create a font of only capital letters */ capitals = extract_font_range(myfont, 'A', 'Z'); /* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy); RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks. SEE ALSO
