PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME         top

       strcspn — get the length of a complementary substring

SYNOPSIS         top

       #include <string.h>

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

DESCRIPTION         top

       The functionality described on this reference page is aligned
       with the ISO C standard. Any conflict between the requirements
       described here and the ISO C standard is unintentional. This
       volume of POSIX.1‐2017 defers to the ISO C standard.

       The strcspn() function shall compute the length (in bytes) of the
       maximum initial segment of the string pointed to by s1 which
       consists entirely of bytes not from the string pointed to by s2.

RETURN VALUE         top

       The strcspn() function shall return the length of the computed
       segment of the string pointed to by s1; no return value is
       reserved to indicate an error.

ERRORS         top

       No errors are defined.
