char* vs char[]

[jicman]

Feliz Navidad.

I have not being reading the newsgroups, because of a few projects
that I have going on.  I am trying to get D into my company.  It's
not going to be easy, but I am positive. :-)

So I have this module that gets some environment variables from the
system.  Here is some code:
//-------------------------------------------------------
extern (C)
{
  char*   getenv  (char *);
  int     putenv  (char *);
}
char[] GetEnv(char[] pSymbol)
{
  return std.string.toString(getenv(pSymbol));
}

int PutEnv(char[] eVar, char[] eVal)
{
  int i = putenv(eVar ~ "=" ~ eVal);
  return i;
}
char[] GetServerName()
{
  // returns the Hostname on the local computer
  char[] sn = GetEnv("COMPUTERNAME");
  return sn;
}
//-------------------------------------------------------

I copied it from the group a few years ago. So, now, with this
new .177 release I get this new error:

..\jic\libs\MyOSEnv.d(32): function jic.libs.MyOSEnv.getenv (char*)
does not match parameter types (char[])
..\jic\libs\MyOSEnv.d(32): Error: cannot implicitly convert
expression (pSymbol) of type char[] to char*
..\jic\libs\MyOSEnv.d(37): function jic.libs.MyOSEnv.putenv (char*)
does not match parameter types (char[])
..\jic\libs\MyOSEnv.d(37): Error: cannot implicitly convert
expression ((eVar) ~ "=" ~ (eVal)) of type char[] to char*

How can I fix this?  Will someone be willing to point me on the
right direction?

Thanks,
