What you say does not make sense.
If you specify a space in the format multiple white space is skipped:



fscanf

"A directive composed of one or more white-space characters is executed by reading input until no more valid input can be read, or up to the first byte which is not a white-space character which remains unread."

Bare scanf is not a great idea, use fgets and sscanf:

something like:

Code:
#include <stdio.h>
#include <string.h>

typedef char buffer[128];


char * chomp(char * line)
{
    char **p = &line;
    strsep(p, "\r\n");
    return line;
}

int main( int argc, char **argv )
{
    buffer      in, out;
    int number;

    while ( fgets(in, sizeof in, stdin) ) {
        chomp(in);
        sscanf(in, "%s %d\n", out, &number); 
        printf("%s = %s %d\n", in, out, number);
    }

    return 0;
}

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 severly screw things up for libcurl. Take care! SEE ALSO
curl_global_init(3), curl_global_cleanup(3), libcurl 7.12.0 10 May 2004 curl_global_init_mem(3)
