[c] How to calculate size of the file from size of the buffer?

Hi,

Can I find size of the file from size of the buffer written?
Code:
nbECRITS = fwrite(strstr(data->buffer, ";") + 1, sizeof(char), (data->buffsize) - LEN_NOM_FIC, fic_sortie);

Thank You Smilie

CURLOPT_BUFFERSIZE(3)					     curl_easy_setopt options					     CURLOPT_BUFFERSIZE(3)

NAME
CURLOPT_BUFFERSIZE - set preferred receive buffer size SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_BUFFERSIZE, long size); DESCRIPTION
Pass a long specifying your preferred size (in bytes) for the receive buffer in libcurl. The main point of this would be that the write callback gets called more often and with smaller chunks. Secondly, for some protocols, there's a benefit of having a larger buffer for per- formance. This is just treated as a request, not an order. You cannot be guaranteed to actually get the given size. This buffer size is by default CURL_MAX_WRITE_SIZE (16kB). The maximum buffer size allowed to set is CURL_MAX_READ_SIZE (512kB). DEFAULT
CURL_MAX_WRITE_SIZE (16kB) PROTOCOLS
All EXAMPLE
TODO AVAILABILITY
Added in 7.10. Growing the buffer was added in 7.53.0. RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. SEE ALSO
CURLOPT_MAX_RECV_SPEED_LARGE(3), CURLOPT_WRITEFUNCTION(3), libcurl 7.54.0 December 20, 2016 CURLOPT_BUFFERSIZE(3)
