    fgets trouble

    Hi all!

    I'm trying to use fgets to read a .txt file. My problem is that the text that i want to be read is in parenthesis. What command should I use to tell fgets to start reading from "(" and stop reading when ")" occurs?

    I'm a newbie and I have no idea how to solve this.

    Thanks in advance for help

    You can't.

    If the parenthesized text spans multiple lines, read the whole file into an array first. If not, you can just work line by line. Either way, you read data in with fgets and then you have a little function which uses strchr() to extract what you want.
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge
