strが指すNULL終端バイト文字列で次のトークンを検索します。区切り文字はdelimが指すNULL終端バイト文字列によって識別されます.Original:
Finds the next token in a null-terminated byte string pointed to by
str. The separator characters are identified by null-terminated byte string pointed to by delim.The text has been machine-translated via Google Translate.

str != NULL場合、この関数は'セパレーターではない最初の文字を検索します。この文字は、トークンのの始まりです。この関数は最初の区切り文字を検索します。この文字は、トークンのエンドです。関数は終了し、トークンの終わりが検出される前にNULLの終わりが検出された場合
strを返します。そうでなければ、トークンの端にポインタが後続の呼び出しのための静的な場所に保存されます。この文字は、その後、NULL文字で置き換え、関数はトークンのの先頭へのポインタを返します。.Original:
If str != NULL, the function searches for the first character which is not separator. This character is the beginning of the token. Then the function searches for the first separator character. This character is the end of the token. Function terminates and returns NULL if end of
str is encountered before end of the token is found. Otherwise, a pointer to end of the token is saved in a static location for subsequent invocations. This character is then replaced by a NULL-character and the function returns a pointer to the beginning of the token.The text has been machine-translated via Google Translate.

str == NULL場合、この関数は、以前の呼び出しで中断したところから続けています。以前に保存されたポインタがstrとして渡されているかのように振る舞いは同じです.
Original:
If str == NULL, the function continues from where it left in previous invocation. The behavior is the same as if the previously stored pointer is passed as str.

#include <cstring> #include <iostream> int main() { char input[100] = "A bird came down the walk"; char *token = std::strtok(input, " "); while (token != NULL) { std::cout << token << '\n'; token = std::strtok(NULL, " "); } }
Output:
A bird came down the walk
