Here are some examples of using 'dd' to accomplish what you are asking:
Code:
# dd outputs 1st 5 bytes of file to screen with diagnostic info
dd if=input_file bs=1 count=5
# dd outputs 1st 5 bytes of file to screen with diagnostic info going to file
dd if=input_file bs=1 count=5 2>test.txt
# dd outputs 1st 5 bytes of file to file with diagnostic info going to file
dd if=input_file bs=1 count=5 of=output_file 2>test.txt

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
