这个函数好用的很， 可以使用某固定字符分割字符串。MSDN上的事例如下：
Example
/* STRTOK.C: In this program, a loop uses strtok
* to print all the tokens (separated by commas
* or blanks) in the string named "string".
*/
#include <string.h>
#include <stdio.h>
char string[] = "A string/tof ,,tokens/nand some more tokens";
char seps[] = " ,/t/n";
char *token;
void main( void )
{
printf( "%s/n/nTokens:/n", string );
/* Establish string and get the first token: */
token = strtok( string, seps );
while( token != NULL )
{
/* While there are tokens in "string" */
printf( " %s/n", token );
/* Get next token: */
token = strtok( NULL, seps );
}
}
Output
A string of ,,tokens
and some more tokens
Tokens:
A
string
of
tokens
and
some
more
tokens
