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 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.
