C程序文本文件中的命令行参数（字符串）

Question

I have ac programm, which needs two arguments (strings). My problem is I need to do an overflow and one argument needs to be 66000 chars long.

So I have a textfile which contains a 66000 chars long string. But how do I pass this string from the file do the c program as an argument?

I already tried: myprog < textFile

But this does not work

OS: Ubuntu.

This is more of a bash question.

If you call:

myprog < textFile

you don't pass textFile as argument, so your c program won't find any argument in char *argv[] . Instead STDIN is taken to come from textFile . Of course you could just read the file content from there, but I understand, you exactly want to pass it as one argument.

So you would call:

myprog "$(cat textFile)"
