Hi,
Can some one tell, how to replace ascii non printable TAB from the while to something, then later on replace it back to TAB.
Basciallz we do bulk data processing, our processin treats TAB as new field ,
So I thought we can replace it with something and later on revert it.

curl_global_init_mem
curl_global_init_mem(3) libcurl Manual curl_global_init_mem(3)
NAME
curl_global_init_mem - Global libcurl initialisation with memory callbacks
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_global_init_mem(long flags,
curl_malloc_callback m,
curl_free_callback f,
curl_realloc_callback r,
curl_strdup_callback s,
curl_calloc_callback c );
DESCRIPTION
This function works exactly as curl_global_init(3) with one addition: it allows the application to set callbacks to replace the otherwise
used internal memory functions.
This man page only adds documentation for the callbacks, see the curl_global_init(3) man page for all the rest. When you use this function,
all callback arguments must be set to valid function pointers.
The prototypes for the given callbacks should match these:
void *malloc_callback(size_t size);
To replace malloc()
void free_callback(void *ptr);
To replace free()
void *realloc_callback(void *ptr, size_t size);
To replace realloc()
char *strdup_callback(const char *str);
To replace strdup()
void *calloc_callback(size_t nmemb, size_t size);
To replace calloc()
CAUTION
Manipulating these gives considerable powers to the application to severely screw things up for libcurl. Take care!
