Hello,
I would like to know how we can highlight/select a section of a file in vi and delete that section if we don't want to use the dd command to delete one line at at time. There is one where we don't want to delete the whole line , but up to a certain word. (2 Replies)

iv_popen
iv_popen(3) ivykis programmer's manual iv_popen(3)NAME
IV_POPEN_REQUEST_INIT, iv_popen_request_submit, iv_popen_request_close - popen(3) for ivykis applications
SYNOPSIS
#include <iv_popen.h>
struct iv_popen_request {
char *file;
char **argv;
char *type;
};
void IV_POPEN_REQUEST_INIT(struct iv_popen_request *this);
int iv_popen_request_submit(struct iv_popen_request *this);
void iv_popen_request_close(struct iv_popen_request *this);
DESCRIPTION
iv_popen provides ivykis(3) applications with an asynchronous version of popen(3) that is integrated with the ivykis event loop.
After initialising a struct iv_popen_request object using IV_POPEN_REQUEST_INIT and assigning its ->file and ->argv and ->type members, one
can call iv_popen_request_submit on it to fork off a child process which will call execvp(2) on ->file and ->argv, while in the parent
process returning a file descriptor that is connected to the child's standard input (if ->type equals "w") or standard output (if ->type
equals "r").
When the application is done with the child process, it should call iv_popen_request_close, and close the file descriptor returned by
iv_popen_request_submit (this is not done automatically).
iv_popen will continue to monitor the child's process state while it is running, by registering an iv_wait(3) interest for its process ID.
If the child process has not yet terminated when iv_popen_request_close is called, iv_popen will attempt to terminate the child process in
the background by sending it a series of SIGTERM and SIGKILL signals.
iv_popen_request_close must be called from the same thread that iv_popen_request_submit was called from on this object.
