Multiline input from stdin

[Satch_fan]

Hi everyone,

I need to read multiple lines (separated by newline) from the stdin stream. If I use fgets(...), it stops reading as soon as it entcounters the first newline (which isn't what I want). I can read from stdin character by character using fgetc(...), but how do I check when the end of input has been reached? comparing fgetc(...) with EOF or '\0' didn't work either. Can anyone help? Can't use '\' at prompt to indicate multiple lines of input either, since ultimately it's not going to be an interactive program.

You're not limited to 1 fgets() call per program. Just call fgets() in a loop until you have all the input you need.

I know that I can use fgets(...) in a loop - but what will the terminating condition be? In other words, how do I know that the contents of stdin have been completely read?

int ch;
while ( ( ch=getchar() ) != EOF ) {
    /* do something */
}

when you finish your input, press ^Z(control + z) if you are using windows, or ^D(control +d) if you are using unix
for example

fjlkfaljk
aaadfffffff
dfdd
^Z

Yuck, sorry for double posting. Antigloss - thanks for replying - I did say in my first post that it's not going to be an interactive program. But maybe I can append the EOF characater at the end of the string before it gets to stdin. Thanks....

Mixing fgets() with other input functions (in particular scanf) is a bad move.

Post actual code if you want a proper answer.
