NAME

       scan_whitenskip - skip whitespace

SYNTAX

       #include <scan.h>

       size_t scan_whitenskip(const char *src,size_t limit);

DESCRIPTION

       scan_whitenskip returns the length of the maximum prefix of src that consists solely of whitespace characters as defined by isspace.

       Normally, this is ' ', 'f', '
', '
', '	', 'v'.

NAME

       strcpy, strlcat, strlcpy, strncat, strncpy, strspn - String operations.

SYNOPSIS

       #include <sys/ddi.h>

       char *strcpy(char *dst, const char *src);

       size_t strlcat(char *dst, const char *src, size_t dstsize);

       size_t  strlcpy(char *dst, const char *src, size_t dstsize);

       char *strncat(char *restrict s1, const char *restrict  s2, size_t n);

       char *strncpy(char *dst, const char *src, size_t n);

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

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       dst, src        Pointers to character strings.

       s1, s2	       Pointers to character strings.

       n	       Count of characters to be copied.

DESCRIPTION

       The  arguments  dst, src, s1 and s2 point to strings. The strcpy(), strlcpy(), strncpy(), strlcat() and strncat() functions all alter their
       first argument. These functions do not check for overflow of the array pointed to by the first argument.

   strcpy()
       The strcpy() function copies characters in the string src to dst, terminating at the first null character in src, and returns  dst  to  the
       caller. No bounds checking is done.

   strncpy()
       The strncpy() function copies src to dst, null-padding or truncating at n bytes, and returns dst. No bounds checking is done.

   strlcpy()
       The  strlcpy()  function copies a maximum of dstsize-1  characters (where dstsize represents the size of the string buffer dst) from src to
       dst, truncating src if necessary.  The result is always null-terminated. The function returns strlen(src). Buffer overflow can  be  checked
       as  follows:

       if (strlcpy(dst, src, dstsize) >= dstsize)
			     return (-1);

   strncat()
       The strncat() function appends  a maximum of n characters. The initial character of s2 overrides the null character at the end  of s1.

   strlcat()
       The  strlcat()  function  appends  a maximum of (dstsize- strlen(dst)-1) characters of src to dst (where dstsize represents the size of the
       string buffer dst). If the string pointed to by dst contains a null-terminated string that  fits  into  dstsize	bytes  when  strlcat()	is
       called, the string pointed to by dst is a null-terminated string that fits in dstsize bytes (including the terminating null character) when
       it completes, and the initial character of src overrides the null character at the end of dst. If the string pointed to by  dst	is  longer
       than  dstsize  bytes  when  strlcat()  is  called,  the	string	pointed  to  by  dst   is  not	changed.  The  function  returns  min{dst-
       size,strlen(dst)}+strlen(src). Buffer overflow can be checked as follows:

       if (strlcat(dst, src, dstsize) >= dstsize)
			     return -1;

   strspn()
       The strspn() function returns the length of the initial segment of string s1 that consists entirely of characters from string s2.

RETURN VALUES

       strcpy(), strncat() and strncpy() return dst.

       For strlcat(), strlcpy() and strspn(), see the Description section.

CONTEXT

       These functions can be called from user or interrupt context.
