man firestring_estr_vsprintfe (Fonctions bibliothèques) - firestring_estr_vsprintfe - firestring_estr_vsprintf(3) with an estring format
NAME
firestring_estr_vsprintfe - firestring_estr_vsprintf(3) with an estring format
SYNOPSIS
#include <firestring.h>
-lfirestring
long firestring_estr_vsprintfe(struct firestring_estr_t *out, struct firestring_estr_t *format, va_list ap)
DESCRIPTION
firestring_estr_vsprintfe() behaves exactly like firestring_estr_vsprintf(3) except that it takes an estring format argument, so the format can contain arbitrary binary data. However, please note that user user-input data as the format string is INSECURE.
RETURN VALUE
Returns the number of bytes written to out.
