Function Documentation

snprintf()

uint64_t snprintf	(	char *	buf,
		uint64_t	bufsz,
		const char *	fmt,
			...
	)

Writes a string to a fixed-capacity buffer according to a format and arguments.

Parameters

buf	Pointer to a buffer where the string is stored.
bufsz	Maximum number of bytes to be used in the buffer.
fmt	Format.

Returns

Number of characters written after truncation, or, if buf == NULL && bufsz == 0, the number of characters to write excluding the null byte.

Note

The result may be truncated to fit in bufsz - 1 bytes. A null character is written after the result in the buffer.
