Overview

These routines operate on null-terminated character strings. They do not check for overflow of any receiving string.

wn_strncpy is NOT the same as "strncpy"; it copies strlen(in) or n chars, whichever is less, and then null terminates. The target can become as long as n+1 chars, including the null-termination.

wn_stracpy allocates (from the current memory group) strlen(in)+1 chars of memory for out, and then copies in to it.

wn_strncat is NOT the same as "strncat"; it appends chars from in while out has strlen < n, and then null terminates. The target can become as long as n+1 chars, including the null-termination.

wn_stracat allocates (from the current memory group) strlen(s1)+strlen(s2)+1 chars of memory for out, then puts the concatonation of s1 and s2 in this memory. wn_stracat3 concatonates 3 strings in the same manner, etc.

wn_char_in_string returns TRUE iff the character c is contained in the null-terminated string s.
