digit hexadecimal

基本解釋

The syntax for specifying a single hexadecimal value is mnemonic where NN is a hexadecimal digit in the range 00 to FF.
用於指定單個(gè)十六進(jìn)制值的語(yǔ)法爲(wèi)助記符，其中 NN 爲(wèi)從 00 到 FF 的十六進(jìn)制數(shù)字。
The escape() function replaces almost any non-alphanumeric ASCII character with % followed by the two-digit hexadecimal code of the encoded character.
escape() 函數(shù)用 % 後跟被編碼字符的兩位 16 進(jìn)制碼代替了幾乎所有非字母數(shù)字的 ASCII 字符。
where [pid] is the process ID, [error code] is an 8-digit hexadecimal code, [file name] is the source code file in the OpenSSL library, and [line] is the line number in that source file.
其中， [pid] 是進(jìn)程 ID， [error code] 是一個(gè) 8 位十六進(jìn)制代碼， [file name] 是 OpenSSL 庫(kù)中的源代碼文件， [line] 是源文件中的行號(hào)。
