curl-library
i receive the http server response messages, but my program coredump in data->set.fwrite
Date: Thu, 23 Sep 2004 18:04:06 +0800
Now i am testing to use libcurl 's methods to communicate with a http server
HTTP Server version:apache-1.3.28 mod_ssl-2.8.15 openssl-0.9.6h[engine]
Curl Version：7.12.0
OS Platform: SunOS cry 5.8 Generic_108528-16 sun4u sparc SUNW,Ultra-60
I send a get method to http server and use the below callback func to store the response message
int cry::callback_receiveFromHTTPServer(void *LOC_H_ptr, size_t LOC_H_size, size_t LOC_H_nmemb, void * LOC_H_data)
{
int LOC_H_ret;
int LOC_H_totalMessageLen = (int)LOC_H_size * (int)LOC_H_nmemb;
tHttpNode_Memory_struct *LOC_H_mem = ( tHttpNode_Memory_struct *)LOC_H_data;
LOC_H_mem->memory = ( char *)ACE_OS::realloc(LOC_H_mem->memory, LOC_H_mem->size + LOC_H_totalMessageLen + 1);
if( LOC_H_mem->memory == NULL )
{
return (COMM_FAILURE);
}
ACE_OS::memcpy(&(LOC_H_mem->memory[LOC_H_mem->size]), LOC_H_ptr, LOC_H_totalMessageLen);
LOC_H_mem->size += LOC_H_totalMessageLen;
LOC_H_mem->memory[LOC_H_mem->size] = 0;
return COMM_SUCCESS;
}
after execute the curl_easy_perform, my program coredump at the place:
wrote = data->set.fwrite(ptr, 1, len, data->set.out);
and I got the following information about "data->set" and ptr below:
