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

u32 * bin_buf
The buffer to place args' binary value

size_t size

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

const char * fmt

The format string to use

va_list args

Arguments for the format string

DESCRIPTION

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

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.
