Clearing file contents
Hi,
Thanks for the reply...
But, as I mentioned earlier if the filesize is very large, say 500MB, then if I use the command ">filename", it will clear the file contents, but, when I do the "ls -l filename" it will will show the file size as 500MB itself, not as 0 bytes.
If the filesize is less, it will work without any problem.
It will be of great help, to get any other UNIX command which will clear the file contents.
Regards,
Raghu

curlopt_infilesize_large
CURLOPT_INFILESIZE_LARGE(3) curl_easy_setopt options CURLOPT_INFILESIZE_LARGE(3)
NAME
CURLOPT_INFILESIZE_LARGE - set size of the input file to send off
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE_LARGE,
curl_off_t filesize);
DESCRIPTION
When uploading a file to a remote site, filesize should be used to tell libcurl what the expected size of the input file is. This value
must be passed as a curl_off_t.
For uploading using SCP, this option or CURLOPT_INFILESIZE(3) is mandatory.
To unset this value again, set it to -1.
When sending emails using SMTP, this command can be used to specify the optional SIZE parameter for the MAIL FROM command.
This option does not limit how much data libcurl will actually send, as that is controlled entirely by what the read callback returns, but
telling one value and sending a different amount may lead to errors.
DEFAULT
Unset
PROTOCOLS
Many
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
curl_off_t uploadsize = FILE_SIZE;
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/destination.tar.gz");
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, uploadsize);
curl_easy_perform(curl);
}
AVAILABILITY
SMTP support added in 7.23.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
