Amaresh,
1: I'm not clear what you mean by "invalid argument" error code.
Your code only tests for return of -1, cannot connect:
if(Gpm_Open(&conn, 0) == -1) ...
Have you got some other code looking for other errors?
What is the numeric value of the return code?
2: Is the mouse type the same on both systems?
Maybe exps2 is not appropriate on the other system.
3: Are you running xterm on one system, and console terminal on another?
return value of -2 is not an error, but an indication of xterm.
regards,
Rodney

Hi,
I am trying to receive mouse event using libgpm library. I have run the GPM
server as
%gpm -m /dev/input/mice -t exps2
The I am trying to open connection with GPM Server using Gpm_open function.
Gpm_open always fails with invalid argument as error code.
Code Snippets:
/****************************************************************************************************/
#include <stdio.h>
#include <gpm.h>
int my_handler(Gpm_Event *event, void *data)
{ printf("Event Type : %d at x=%d y=%d\n", event->type, event->x,
event->y);
return 0;
}
int main()
{ Gpm_Connect conn;
int c;
conn.eventMask = ~0; /* Want to know about all the events */
conn.defaultMask = 0; /* don't handle anything by default */
conn.minMod = 0; /* want everything */
conn.maxMod = ~0; /* all modifiers included */
if(Gpm_Open(&conn, 0) == -1)
{
perror("Cannot connect to mouse server\n");
return 0;
}
gpm_handler = my_handler;
while((c = Gpm_Getc(stdin)) != EOF)
printf("%c", c);
Gpm_Close();
return 0;
}

I am using GPM version 1.19.6. The above code is working on one of my
server but throwing error on another.
Can some one help me to resolve the issues?
