.SH NAME
firestring_estr_vsprintf \-
.BR snprintf (3)
into an estring
.SH SYNOPSIS
.B #include <firestring.h>
.br
.B -lfirestring
.LP
.BI "long firestring_estr_vsprintf(struct firestring_estr_t *" "out" ", const char * const " "format" ", va_list " ap ")"
.SH DESCRIPTION
firestring_estr_vsprintf() behaves exactly like
.BR firestring_snprintf (3)
except that it writes to an estring (which contains
the size internally, so size is not needed as a
parameter), and it takes an stdarg object instead of a list of arguments.
.SH RETURN VALUE
Returns the number of bytes written to
.IR out .
