Therefore usage of sprintf often - results in possible entries for buffer overrun attacks. So please - use this version only if you are sure the call is safe. sprintf - allways terminstes the buffer it writes to. - -snprintf knows the buffers size and will not write behind it. But you will - have to use either a static buffer or allocate a dynamic buffer - before beeing able to call the function. In other words you must - be sure that you really know the maximum size of the buffer required. - A bad thing is having a big maximum while in most cases you would - only need a small buffer. If the size of the resulting string is - longer or equal to the buffer size than the buffer is not terminated. - -spprintf is the dynamical version of snprintf. It allocates the buffer in size - as needed and allows a maximum setting as snprintf (turn this feature - off by setting max_len to 0). spprintf is a little bit slower than - snprintf and offers possible memory leakes if you miss freeing the - buffer allocated by the function. Therfore this function should be - used where either no maximum is known or the maximum is much bigger - than normal size required. spprintf allways terminates the buffer. - -Example: - - #define MAX 1024 | #define MAX 1024 | #define MAX 1024 - char buffer[MAX] | char buffer[MAX] | char *buffer; - | | - | | // No need to initialize buffer: - | | // spprintf ignores value of buffer - sprintf(buffer, "test"); | snprintf(buffer, MAX, "test"); | spprintf(&buffer, MAX, "text"); - | | if (!buffer) - | | return OUT_OF_MEMORY - // sprintf allways terminates | // manual termination of | // spprintf allays terminates buffer - // buffer | // buffer *IS* required | - | buffer[MAX-1] = 0; | - action_with_buffer(buffer); | action_with_buffer(buffer); | action_with_buffer(buffer); - | | efree(buffer); -*/ - -#ifndef SNPRINTF_H -#define SNPRINTF_H - -#if !defined(HAVE_SNPRINTF) || PHP_BROKEN_SNPRINTF -extern int ap_php_snprintf(char *, size_t, const char *, ...); -#define snprintf ap_php_snprintf -#endif - -#if !defined(HAVE_VSNPRINTF) || PHP_BROKEN_VSNPRINTF -extern int ap_php_vsnprintf(char *, size_t, const char *, va_list ap); -#define vsnprintf ap_php_vsnprintf -#endif - -#if PHP_BROKEN_SPRINTF -int php_sprintf (char* s, const char* format, ...); -#define sprintf php_sprintf -#endif - -typedef enum { - NO = 0, YES = 1 -} boolean_e; - -extern char * ap_php_cvt(double arg, int ndigits, int *decpt, int *sign, int eflag, char *buf); -extern char * ap_php_ecvt(double arg, int ndigits, int *decpt, int *sign, char *buf); -extern char * ap_php_fcvt(double arg, int ndigits, int *decpt, int *sign, char *buf); -extern char * ap_php_gcvt(double number, int ndigit, char *buf, boolean_e altform); - -#define WIDE_INT long -typedef WIDE_INT wide_int; -typedef unsigned WIDE_INT u_wide_int; - -typedef int bool_int; - -extern char * ap_php_conv_10(register wide_int num, register bool_int is_unsigned, - register bool_int * is_negative, char *buf_end, register int *len); - -extern char * ap_php_conv_fp(register char format, register double num, - boolean_e add_dp, int precision, bool_int * is_negative, char *buf, int *len); - -extern char * ap_php_conv_p2(register u_wide_int num, register int nbits, - char format, char *buf_end, register int *len); - - -#endif /* SNPRINTF_H */ - -/* - * Local variables: - * tab-width: 4 - * c-basic-offset: 4 - * End: - */ |
