[C] fgets problem with SIGINT singlal!!!

Applications Programming
1

Hi all,

I have this method to read a string from a STDIN:

void readLine(char* inputBuffer){

    fgets (inputBuffer, MAX_LINE, stdin);
    fflush(stdin);

    /* remove '\n' char from string */
    if(strlen(inputBuffer) != 0)
        inputBuffer[strlen(inputBuffer)-1] = '\0';

}

All work fine but if i catch SIGINT signal (CTRL+C) with this method:

void handle_SIGNINT(){

    /* here i don't want exit with program!!! */

}

i would like that "fgets's wait" was released when there is a signal....now to realese it i need press ENTER KEY!!!, how can i do in automate?

can i "simulate" the ENTER key pressed writing a particular ASCII char into STDIN???

Thanks a lot in advance, Martin

#include <errno.h>
#include <stdio.h>

#include <stdlib.h>

void readLine(char *inputBuffer)
{
    char *p=NULL;
    *inputbuffer=0x0;
    if(fgets (inputBuffer, MAX_LINE, stdin)==NULL)
    {
        if(feof(stdin)) return;
    	if(errno == EINTR)
    	{
    	    *readLine=0x0; /* or do what you want to a partial read */
    		return;
    	}
    	/* other errors */
    	perror("Fatal error on stdin");
    	exit(1);    	
    }
    /* fflush(stdin) is NOT a defined operation 
       if this actually works it is "programming by accident" 
       
    */		
    fflush(stdin);

    /* remove '\n' char from string */
    /* if the string entered is greater than MAX_LINE
       then you are whacking off valid characters
       
    if(strlen(inputBuffer) != 0)
        inputBuffer[strlen(inputBuffer)-1] = '\0';
        I am assuming MAX_LINE is defined by you and is not some system value
        try this instead:
    */
    p=strchr(inputBuffer, '\n');
    if(p!=NULL)
    	*p=0x0;

}

fgets handles SIGINT all by itself - don't need to call a signal handler for SIGINT or leave the SIGINT handler as it is by adding code as above.
