The first time we call the function, we need to pass thequotestring to specify that it is the source string parametersrc. char* word = strtok(quote," "); All subsequent calls to thestrtok()function takeNULLas thesrcparameter. This argument instructs the compiler to use the previously-used...
On the first call tostrtok, the function skips leading delimiters and returns a pointer to the first token instrToken, terminating the token with a null character. More tokens can be broken out of the remainder ofstrTokenby a series of calls tostrtok. Each call tostrtokmo...
return 0; } MSDN上的原话: On the first call to strtok, the function skips leading delimiters and returns a pointer to the first token in strToken, terminating the token with a null character. More tokens can be broken out of the remainder of strToken by a series of calls to strtok. Eac...
The strtok() function returns a pointer to the next "token" in str1, where str2 contains the delimiters that determine the token. strtok() returns NULL if no token is found. In order to convert a string to tokens, the first call to strtok() should have str1 point to the string to ...
今天才知道原来C语言也有类似java的split的函数,按特定字符串对字符串进行分解:ﻫ strtok的解释和示例: ﻫ strtok ﻫ Syntax:ﻫ view plain ﻫ #include <cstring> char *strtok( char *str1, const char *str2 ); Thestrtok() function returns a pointer to the next "token" in str1, where...
The function then returns the pointer to the beginning of the token Ifstris a null pointer, the call is treated as a subsequent call tostrtok: the function continues from where it left in previous invocation. The behavior is the same as if the previously stored pointer is passed asstr. ...
This function validates its parameters. When an error condition occurs, as in the Error Conditions table, the invalid parameter handler is invoked, as described inParameter validation. If execution is allowed to continue, these functions seterrnotoEINVALand returnNULL. ...

strtok的函数原型为char *strtok(char *s, char *delim)，功能为“Parse S into tokens separated by characters in DELIM.If S is NULL, the saved pointer in SAVE_PTR is used as the next starting point. ” 翻译成汉语就是：作⽤于字符串s，以包含在delim中的字符为分界符，将s切分成⼀个个⼦...
1)Finds the next token in a null-terminated byte string pointed to bystr. The separator characters are identified by null-terminated byte string pointed to bydelim. This function is designed to be called multiples times to obtain successive tokens from the same string. ...
