@MacMonster Thanks because of it i was getting segmentation fault although i dont know why my format is wrong because i wasn't getting any compilation error.
@alister although I haven't written here I am checking for correct memory allocation.So that isn't the culprit.
Regards,
Rajsekhar

Ns_Alloc(3aolserver) AOLserver Library Procedures Ns_Alloc(3aolserver)
__________________________________________________________________________________________________________________________________________________
NAME
ns_calloc, ns_free, ns_malloc, ns_realloc - Memory allocation functions
SYNOPSIS
#include "ns.h"
void *
ns_calloc(size_t num, size_t esize)
void
ns_free(void *ptr)
void *
ns_malloc(size_t size)
void *
ns_realloc(void *ptr, size_t size)
_________________________________________________________________
DESCRIPTION
The AOLserver memory storage allocation code was moved into Tcl core beginning with Tcl 8.4.0. Starting with AOLserver 3.5, these memory
allocation functions are wrappers that call Tcl_Alloc and Tcl_Free. Earlier versions of AOLserver used this fast memory storage allocator
internally, or the platform's memory allocator depending on how you configured it.
The actual amount of memory allocated or freed will be different from the requested amount. This is because the fast memory allocation
code pools memory into chunks and manages that memory internally. In addition, the Tcl distribution may be compiled to allocate even more
memory which is used internally for diagnostic reasons. Using ns_free to free memory created by routines other than ns_malloc, ns_realloc
and ns_calloc will almost certainly result in segmentation faults or undefined behavior.
The lowercase and mixed-case versions are identical; the lowercase versions are preferred.
ns_calloc(num, esize)
Allocates a block of memory that is num * esize large, zeros it, and returns a pointer to the beginning of the memory block or NULL
if the operation fails.
ns_free(ptr)
ns_free() frees the memory space pointed to by ptr. This pointer must have been created with a previous call to ns_malloc(), ns_cal-
loc() or ns_realloc(). If ptr is NULL, no operation is performed. ns_free() returns no value.
ns_malloc(size)
ns_malloc() allocates size bytes and returns a pointer to the allocated memory. The memory is not cleared. The value returned is a
pointer to the allocated memory or NULL if the request fails. The memory must be freed by ns_free.
ns_realloc(ptr, size)
ns_realloc changes the size of the memory block pointed to by ptr to size bytes. The contents will be unchanged to the minimum of
the old and new sizes. Newly allocated memory will be uninitialized. If ptr is NULL, the call is equivalent to ns_malloc(size); if
size is equal to zero, the call is equivalent to ns_free(ptr). Unless ptr is NULL, it must have been returned by an earlier call to
ns_malloc(), ns_calloc() or ns_realloc().
