strcspn(3)                          CLIX                          strcspn(3)



  NAME

    strcspn - Finds the longest initial occurence of one string of characters
    in another

  LIBRARY

    Standard C Library (libc.a)

  SYNOPSIS

    #include <string.h>

    size_t strcspn(
      char * string1 ,
      char * string2 );

  PARAMETERS

    string1
           A pointer to a character string

    string2
           A pointer to a character string

  DESCRIPTION

    The strcspn() function computes the length of the maximum initial segment
    of the string pointed to by the string1 parameter, which consists entirely
    of characters that are not from the string pointed to by the string2
    parameter.

  EXAMPLES

    #include <stdio.h>
    #include <string.h>

    main()
    {
         size_t sub_len;
         char *string1, *vowels;

         string1 = "hello world!";
         vowels = "aeiou";

         /* the sub_len will be 1 since the second character of string1 is an `e' */
         sub_len = strcspn(string1, vowels);

         printf("The length of the initial segment of `%s' which consists\n", string1);
         printf("entirely of characters not from `%s' is %d\n", vowels, sub_len);
