Top Forums UNIX for Advanced & Expert Users Map snps into a ref gene file Post 302989923 by Don Cragun on Thursday 19th of January 2017 08:47:30 PM

And what output are you trying to get from the two sample input files you provided?

What happens if there is no ID in the 1st file that appears in a range specified by the 2nd file?

What happens if there is more than one ID in the 1st file that fits in a range specified by a single line in the 2nd file?

What happens if there is no range in the 2nd file for a position specified in the 1st file?

What have you tried to solve this problem on your own?

setjmp(3)						     Library Functions Manual							 setjmp(3)

Name
       setjmp, longjmp - non-local goto

Syntax
       #include <setjmp.h>

       int setjmp (env)
       jmp_buf env;

       void longjmp (env, val)
       jmp_buf env;
       int val;

Description
       The and functions help deal with errors and interrupts encountered in a low-level subroutine of a program.

       The function saves its stack environment in env (whose type, jmp_buf, is defined in the <setjmp.h> header file) for later use by It returns
       the value 0.

       The function restores the environment saved by the last call of with the corresponding env argument.   After  finishes,	program  execution
       continues  as if the corresponding call of (which must not itself have returned in the interim) had just returned the value val.  The func-
       tion cannot cause to return the value 0.  If is invoked with a second argument of 0, returns 1.	At the time of the second return from  all
       accessible  data  have  values as of the time is called.  However, global variables have the expected values.  For example, those as of the
       time of the

Examples
       #include <setjmp.h>

       jmp_buf env;
       int i = 0;
       main ()
       {
	    void exit();

	    if(setjmp(env) != 0) {
		 (void) printf("value of i on 2nd return from setjmp: %d0, i);
		 exit(0);
	    }
	    (void) printf("value of i on 1st return from setjmp: %d0, i);
	    i = 1;
	    g();
	    /*NOTREACHED*/
       }

       g()
       {
	    longjmp(env, 1);
	    /*NOTREACHED*/
       }

       If the a.out resulting from this C language code is run, the output is as follows:
       value of i on 1st return from setjmp:0

       value of i on 2nd return from setjmp:1
       Unexpected behavior occurs if is called without a previous call to or when the last such call was in a function which has since returned.

Restrictions
       The values of the registers on the second return from are register values at the time of the first call to not those of the Thus, variables
       in a given function can produce unexpected results in the presence of depending on whether they are register or stack variables.
