sprintf formating data?

[drzsmith]

hi when using sprintf for a value which is less than the width specifier the extra spaces are paded with spaced (0x20)

for exsample

code
num = 1234
length = sprintf(buf,%8d,num)

code

length = 8 (1234 space space space space), can null be used rather than a space?

thanks

You would have to rewrite/modify the routine.

However, I believe the string library routines contained in string.h would be more applicable to your requirements as they typically terminate the string with a NULL.

Checkout, strcpy() and strcat():

cstring (string.h)
