Assuming you're talking about text files:
A. suck the whole thing up in memory, change it there, write it back out.
B. open a temp, copy till the line of interest, write your change,
copy remainder. mv/cp the temp to the original.
C. read to line of interest, ftell(), suck remainder into memory.
ftruncate(), fseek(), write your changes, write out the remainder.
