The standard function in the C programming language library for printing formatted output.The first argument is a format string which may contain ordinary characters which are just printed and "conversion specifications" - sequences beginning with '%' such as %6d which describe how the other argume...

If the function takes a wchar_t buffer, the size specifies the number of 16-bit words. Let len be the size of the formatted data. If the function takes a char buffer, the size is in bytes. If the function takes a wchar_t buffer, the size specifies the number of 16-...
Stores formatted output in a string buffer #include <stdio.h> intsnprintf( char * restrict dest, size_t n, const char * restrict format, ... ); The snprintf() function is similar to printf(), but writes its output as a string in the buffer referenced by the first pointer argument,...

The_snprintffunction formats and stores count or fewer characters and values (including a terminating null character that is always appended unless count is zero or the formatted string length is greater than or equal to count characters) in buffer. ...

normally calling fgets, strncat, and strncpy instead. Even better are the more recently available function strlcat and strlcpy, which ensure the result is a properly terminated string. Additional tips on writing secure network programs are found in Chapter 23 of [Garfinkel, Schwartz, and Spafford ...

The format consists of ordinary characters and has the same form and function as theformatargument forprintf. If copying occurs between strings that overlap, the behavior is undefined....
