C function strtok()

Syntax:

#include <string.h>char *strtok( char *str1, const char *str2 );

Description:
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 be tokenized. All calls after this should have str1 be NULL.

Example:

char str[] = "now # is the time for all # good men to come to the # aid of their country";char delims[] = "#";char *result = NULL;result = strtok( str, delims );while( result != NULL ) {    printf( "result is /"%s/"/n", result );    result = strtok( NULL, delims );}OUTPUT:  result is "now "  result is " is the time for all "  result is " good men to come to the "  result is " aid of their country"
