strlen

常見例句

• The strlen() function returns the length of a string.
  函數(shù)的作用是：返廻字符串長(zhǎng)度。
• We can use this fact to write another version of strlen, which computes the length of a string.
  如果要更詳細(xì)的了解，建議還是把這章細(xì)讀一遍。
• When we call strlen, it returns the number of characters in a zero-terminated array of single-byte characters.
  許多年來，許多人一直將字符串作爲(wèi)一系列單字節(jié)字符來進(jìn)行編碼，竝在結(jié)尾処加上0.
• The strlen() call was there only to make sure the value is actually accessed....
  如果在聲明中用表達(dá)式的結(jié)果對(duì)其賦值會(huì)導(dǎo)致解析錯(cuò)誤。
• BTW: if you want to call recv() with the maximal length of return_msg, please use sizeof(return_msg) instead of strlen(return_msg).
  但是就是不明白爲(wèi)什麼如果接受的長(zhǎng)度大於了實(shí)際返廻的長(zhǎng)度就可能出現(xiàn)我上述的那種情況呢（好像不是所有的時(shí)候都那樣）！
• The standard library function strlen(s) returns the length of its character string argument s,excluding the terminal ‘\0’.
  內(nèi)部表示字符串時(shí)，要用一個(gè)空字符‘\\0’來結(jié)尾，所以實(shí)際存儲(chǔ)該字串的存儲(chǔ)單元比括在雙引號(hào)中的字符多一個(gè)。）
