This is how I have I have the code in my c program

Code:
strcpy(s, "sed '1,'\\\"`wc -l < $tmp/AA `\\\"'d' /tmp/BB > /tmp/CC");
system(s);

The expression doesnt get me any value. When I have the code without the expression as mentioned below, it works.

Code:
strcpy(s, "sed '1,3d' /tmp/AA > /tmp/CC");
system(s);

Is there any alternate way to do this in the unix

XkbAllocGeomOverlayRows(3)					   XKB FUNCTIONS					XkbAllocGeomOverlayRows(3)

NAME
XkbAllocGeomOverlayRows - Allocate rows in a overlay SYNOPSIS
Status XkbAllocGeomOverlayRows (XkbOverlayPtr overlay, int num_needed); ARGUMENTS
- overlay section for which rows should be allocated - num_needed number of new rows required DESCRIPTION
Xkb provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these functions to create or modify key- board geometries. Note that these functions merely allocate space for the new element(s), and it is up to you to fill in the values explicitly in your code. These allocation functions increase sz_* but never touch num_* (unless there is an allocation failure, in which case they reset both sz_* and num_* to zero). These functions return Success if they succeed, BadAlloc if they are not able to allocate space, or BadValue if a parameter is not as expected. XkbAllocGeomOverlayRows allocates num_needed rows and adds them to the overlay. No initialization of the rows is done. To free rows in an overlay, use XkbFreeGeomOverlayRows. DIAGNOSTICS
BadAlloc Unable to allocate storage BadValue An argument is out of range SEE ALSO
XkbFreeGeomOverlayRows(3) X Version 11 libX11 1.6.0 XkbAllocGeomOverlayRows(3)
