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.
