.SH "NAME"
vbin_printf \- Parse a format string and place args\*(Aq binary value in a buffer
.SH "SYNOPSIS"
.HP \w'int\ vbin_printf('u
.BI "int vbin_printf(u32\ *\ " "bin_buf" ", size_t\ " "size" ", const\ char\ *\ " "fmt" ", va_list\ " "args" ");"
.SH "ARGUMENTS"
.PP
\fIu32 * bin_buf\fR
.RS 4
The buffer to place args\*(Aq binary value
.RE
.PP
\fIsize_t size\fR
.RS 4
The size of the buffer(by words(32bits), not characters)
.RE
.PP
\fIconst char * fmt\fR
.RS 4
The format string to use
.RE
.PP
\fIva_list args\fR
.RS 4
Arguments for the format string
.RE
.SH "DESCRIPTION"
.PP
The format follows C99 vsnprintf, except
\fBn\fR
is ignored, and its argument is skipped\&.
.PP
The return value is the number of words(32bits) which would be generated for the given input\&.
.SH "NOTE"
.PP
If the return value is greater than
\fIsize\fR, the resulting bin_buf is NOT valid for
\fBbstr_printf\fR\&.
