STRCSPN(3)               BSD Library Functions Manual               STRCSPN(3)

NAME
     strcspn -- span the complement of a string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

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

DESCRIPTION
     The strcspn() function spans the initial part of the null-terminated string s1, as long as the charac-ters characters
     ters from s1 do not occur in string s2 (it spans the complement of s2).  In other words, it computes
     the string array index in s1 of the first character of s1 which is also in s2, else the index of the
     first null character.

RETURN VALUES
     The strcspn() function returns the number of characters spanned.

SEE ALSO
     memchr(3), strchr(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

STANDARDS
     The strcspn() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
