SYNOPSIS

#include <wn/wnstr.h>
wn_strncpy(out,in,n)
char out[],in[];
int n;
wn_stracpy(&out,in)
char out[],in[];
wn_strncat(out,in,n)
char out[],in[];
int n;
wn_stracat(&out,s1,s2)
char out[],s1[],s2[];
wn_stracat3(&out,s1,s2,s3)
char out[],s1[],s2[],s3[];
wn_stracat4(&out,s1,s2,s3,s4)
char out[],s1[],s2[],s3[],s4[];
wn_stracat5(&out,s1,s2,s3,s4,s5)
char out[],s1[],s2[],s3[],s4[],s5[];
wn_stracat6(&out,s1,s2,s3,s4,s5,s6)
char out[],s1[],s2[],s3[],s4[],s5[],s6[];
bool wn_char_in_string(c,s)
char c,s[];

DESCRIPTION

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 termi

nates. 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-termi

nation.

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 concato

nates 3 strings in the same manner, etc.

wn_char_in_string returns TRUE iff the character c is con

tained in the null-terminated string s.
