firestring_estr_vsprintf(3)

NAME
firestring_estr_vsprintf - snprintf(3) into an estring

SYNOPSIS
#include <firestring.h>
-lfirestring

long firestring_estr_vsprintf(struct firestring_estr_t *out, const char * const format, va_list ap)

DESCRIPTION
firestring_estr_vsprintf() behaves exactly like 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.

RETURN VALUE
Returns the number of bytes written to out.
