函数名称：string_escape_mem - quote characters in the given memory buffer*@src: source buffer (unescaped)*@isz: source buffer size*@dst: destination buffer (escaped)*@osz: destination buffer size*@flags: combination of the flags*@only: NULL-terminated string

函数原型：int string_escape_mem(const char *src, size_t isz, char *dst, size_t osz, unsigned int flags, const char *only)

返回类型：int

参数：

类型参数名称
const char *src
size_tisz
char *dst
size_tosz
unsigned intflags
const char *only
500  p等于dst
501  end等于p加osz
502  is_dict等于only且only
504  当isz自减循环
505  c等于src自加
518  如果flags按位与ESCAPE_NP且isprint(c)或is_dict且非strchr(only, c)则否则
522  如果flags按位与ESCAPE_SPACE且escape_space(c, & p, end)则继续下一循环
525  如果flags按位与ESCAPE_SPECIAL且escape_special(c, & p, end)则继续下一循环
528  如果flags按位与ESCAPE_NULL且escape_null(c, & p, end)则继续下一循环
532  如果flags按位与ESCAPE_OCTAL且escape_octal(c, & p, end)则继续下一循环
535  如果flags按位与ESCAPE_HEX且escape_hex(c, & p, end)则继续下一循环
539  escape_passthrough(c, & p, end)
542  返回:p减dst
