constchar* strpbrk(constchar* dest,constchar* breakset); | ||
char* strpbrk( char* dest,constchar* breakset); | ||
Scans the null-terminated byte string pointed to bydest for any character from the null-terminated byte string pointed to bybreakset, and returns a pointer to that character.
Contents |
| dest | - | pointer to the null-terminated byte string to be analyzed |
| breakset | - | pointer to the null-terminated byte string that contains the characters to search for |
Pointer to the first character indest, that is also inbreakset, or null pointer if no such character exists.
The name stands for "string pointer break", because it returns a pointer to the first of the separator ("break") characters.

Output:
" world, friend of mine!"", friend of mine!"" of mine!"" mine!""!"There are 5 words
