You can use logsave command to save the output of a command in a logfile. General syntax is as follows:
logsave /path/to/logfile command-name argument(s)
The logsave program will execute command-name with the specified argument(s), and save a copy of its output to logfile. If the containing directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will also be written to standard output. If command-name is a single hyphen (-), then instead of executing a program, logsave will take its input from standard input and save it in logfile
logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to /var/log. For example, save output of ls command to output.log file:
logsave /tmp/output.txt ls
For example run lftp and save remote server file list to /tmp/filelist.txt for other scripts:
logsave /tmp/filelist.txt 'lftp -u -e "cd pub;ls;quit;" admin,mypassword ftp.nixcraft.in '

But is it possible to execute the same thing using c code, but by calling functions? I need to know how to do the following in c code:
command > textfile
how to execute the “>” in c code? In other words how to I pipe the output in the terminal to a text file in c code? Are there any functions available?
The temporary solution I have is to make a system call to execute the above command within my c code.
system(command);
Is there any other way?
