Is this a string ? Does it have a zero byte at the end, to make it a string ?
If so, then use the strlen() function to get the length of the string.
Then use a for() loop to step through each byte in the string, and
copy each one to another buffer. Inside the for() loop, read a char
from the first buffer, and use an if() statement to check if the char
is either a CR or a LF. If so, then skip copying that character to
the 2nd buffer. Also, when you finish copying the chars to the 2nd
buffer, make sure you write a zero byte at the end, so it will become
a string. |
