Name

vbin_printf — Parse a format string and place args' binary value in a buffer

Synopsis

int vbin_printf (u32 *  bin_buf,
 size_t  size,
 const char *  fmt,
 va_list  args);

Arguments

bin_buf

The buffer to place args' binary value

size

The size of the buffer(by words(32bits), not characters)

fmt

The format string to use

args

Arguments for the format string

Description

The format follows C99 vsnprintf, except n is ignored, and its argument is skiped.

The return value is the number of words(32bits) which would be generated for the given input.

NOTE

If the return value is greater than size, the resulting bin_buf is NOT valid for bstr_printf.
