NAME
BIO_printf,
BIO_vprintf,
BIO_snprintf,
BIO_vsnprintf —
formatted output to a BIO
SYNOPSIS
#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);
DESCRIPTION
BIO_vprintf() is a wrapper around
vfprintf(3),
sending the output to the specified bio.
BIO_printf() is a wrapper around
BIO_vprintf().
BIO_snprintf() and
BIO_vsnprintf() are wrappers around
vsnprintf(3).
RETURN VALUES
These functions return the number of bytes written, or -1 if an error occurs. In contrast to snprintf(3) and vsnprintf(3),BIO_snprintf() and
BIO_vsnprintf() also return -1 if
n is too small to hold the complete output.
