#include <openssl/bio.h> int BIO_printf(BIO *bio, const char *format, ...) int BIO_vprintf(BIO *bio, const char *format, va_list args) int BIO_snprintf(char *buf, size_t n, const char *format, ...) int BIO_vsnprintf(char *buf, size_t n, const char *format, va_list args)
BIO_vprintf() is similar to the vprintf() function found on many platforms, the output is sent to the specified BIO, bio, rather than standard output. All common format specifiers are supported. The argument list args is a stdarg argument list.
BIO_snprintf() is for platforms that do not have the common snprintf() function. It is like sprintf() except that the size parameter, n, specifies the size of the output buffer.
BIO_vsnprintf() is to BIO_snprintf() as BIO_vprintf() is to BIO_printf().
