Should be quite simple.
Just read the whole file into memory, an array of char buff[80] say, allocated dynamically according to the size of the file, then you can just read it with an incrementing index.
If you have different files for different positions, just means multi-dimensional arrays, one index for the physical position and another for the position in the file for that place.
Mine was just a very simple example, to show that feeding lines through a component worked.

This is a simple example of what I mean, using the previous example as the basis.
It is just using a single dimemsional array of char* each holding a line from the file.
It compiles, but I haven't had time to test it

It is possible that you don't want to use the G-code interpreter at all.
A userspace component that calculates axis positions can command axis moves directly.
But even that might be too high-level. It is perfectly possible to pass axis positions directly to stepgen (for example) and just have the motors go there. The internal acell and velocity limits mean that stepgen is itself a very simple motion planner for one axis at a time.
If your code is calculating positions on the fly, then outputting those positions directly to HAL can work.

the idea of reading an external file to mycomponent.comp is very good but does not work in my case.
In fact in my case I write only one xyz position at a time.
This means that at each new location, the system waits the time of writing and reading of the pc. This generates a time when the axes are still waiting for a new command.
I need a lot lower this time.

sorry for late reply .... but I have my holiday.
to in an attempt to follow the ideas that came from the suggestions of ArkEye ... I mek this code on new mycomp
this is incomplete and put the pid of my applycation manually now ... it's only a test ..... I grab motion.in-position signal by hal and transform it in to UNIX signal USR1 ... In my QT application I use this signal to generate new mdi row with xyz pos and send it to linuxcnc ..... every new motion.in-position send a new mdi row ....
Unfortunately, I have this error during compilation:
I don't Know how to solve this ....flag is not a solution ... I need some suggestion ....
@ andypugh ..... thanks ... But eventually I should send positions found directly to mydeltakins-withlimitfunc.comp .... I think is possible pass the position to hal and than to mydeltakins-withlimitfunc.comp but how to? .... how to send new position to hal from qt program? Is possible to comunicate with deltakins.comp whit a standard C/C++ pipe?

Hi
kill() seems to be one system command that varies from system to system and kernel version to version
This is a simple program adapted from the GNU examples which builds and runs on Wheezy 3.2.0-4-rt-amd64
You don't need <sys/posix_types.h> just these headers and don't have to set _POSIX_C_SOURCE
Be aware that after kernels 2.6.38 ish, the headers started to be moved around
Both Wheezy and Ubuntu 12.04 have a directory called /usr/include/x86_64_linux_gnu (or i386_linux_gnu depending upon system type)
This directory contains /sys /bits /asm etc
I always symlink the contents back to the parent directory or a lot of older code will not build.

First - I use ubuntu 10.04.... second - Sorry but I have some real problem with my idea .... I create a new myUNIXsignal-sender.c and I install it with:
The code that I use is only for testing ..... I don't now if is correctly written ... i Think is only a botched ..... but I use it for some experiments ....
Is you see I find in every way to correctly compile whit signal.h and other library .... but I receive only compile error .... I make various symlink in my system for correctly cath the system library .... but linuxcnc don't accept it .... than I use only hal.h etc and I hope that "kill" function is bring .... but I have no result.
My QT program is created for bring UNIX signal ... if test it from terminal I can correctly use " kill -SIGUSR1 qtpgrPID" .... My QT program bringh correctly this signal and send correctly to linuxcnc/axis a new line similar to this:
In myUNIXsignal-sender.c I would like to send a kill signal whenever I get a bit from hal (motion.in-position or position axis.1.in-bit).
Actually the major problem is probabily the symlink ... I have create symlink .... for example locate signal.h have this output:
I not have other ideas for solve my problem now. Your example is ok but I need lauch unix signal from my comp not receive it. At any case I'm unable to compile your code .... I think for bad symlink.

Replied by bkt on topic c++ grab in position signal
If I compile this simple progrma whit g++ test1.c -o test1 ... the compile is ok and the axis + test1.c + my qt program work perfectly ....
I try to make this simple thing but using a linuxcnc comp that grab motion.in-position or axis.1.in-position myhal.h signal ..... I hope I was clear ... my English is bad I admit.
I try to not use ncg file at all.
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <string.h>
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>
#include <signal.h>
int main(void)
{
kill(17175, SIGUSR1);
printf("\n signal send \n");
return 0;

Just stuff as it occured to me, not had a chance to look through properly, but this jumped out
You have effectively re-defined kill and it calls itself recursively.
It also takes arguments and then ignores them anyway.
Just for the sake of sanity I would call it kill_local or something.
perhaps
int local_kill ( )
{
int retval = kill(15962, SIGUSR1);
return retval;
}
regards
int kill (int pdi, int s){ kill(15962, SIGUSR1); return 0;}
