strcspn

Prototype

char *strcspn(char * s1, char *s2);

Description Function computes the length of the maximum initial segment of the string pointed to by s1 that

consists entirely of characters that are not in the string pointed to by s2.

The function returns the length of the initial segment.

Example

char txt = “mikroElektronika”;

char txt_sub = “mikro”;

char *res;

res = strcspn(txt_sub,txt);

strpbrk

Prototype

char *strpbrk(char * s1, char *s2);

Description Function searches s1 for the rst occurrence of any character from the string s2. The terminating null

character is not included in the search. The function returns pointer to the matching character in s1. If

s1 contains no characters from s2, the function returns 0.

Example

char txt = “mikroElektronika”;

char txt_sub = “mikro”;

char *res;

res = strpbrk(txt_sub,txt);

strrchr

Prototype

char *strrchr(char * ptr, char chr);

Description Function searches the string ptr for the last occurrence of character chr. The null character

terminating ptr is not included in the search. The function returns pointer to the last chr found in

ptr; if no matching character was found, function returns 0.

Example

char txt = “mikroElektronika”;

res = strrchr(txt_sub,’k’); // returns the pointer to the ‘k’ character of

the ‘txt’ string
