snprintf functionality in Poco

[pocouser]

hi i want the data in form of first 5 bytes stores length of the data in text format and remaining bytes will have the actual data.

in c we can use
int Datasize = sizeof(datastruct);
snprintf(Datatosendbuffer, lnLength, "%05d", Datasize);

after copying the length of the data in text format the actual data will be copied in Datatosendbuffer buffer.

I want to know how in poco do we get the above functionality of snprintf?
Thanks

See the format function in Poco/Format.h and the NumberFormatter class in Poco/NumberFormatter.h. Alternatively, you can use iostreams (e.g., std::stringstream).
