error: conversion from 'PString' to non-scalar type 'String'

I’m getting the error in the subject when trying to pass a string generated by PString to a function. Can some knowledgeable person tell me what do I need to do to resolve this?

Thanks in advance…

void loop() {

  if (client.isConnected()) {
    Serial.println("Old connection active. Closing");
    client.close();
  }

  PString postData(buffer, sizeof(buffer));
  postData.print("1,"); 
  postData.print(millis());

  Serial.print(postData);
  Serial.print(" - ");

  cosm(postData);

  while (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.isConnected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.close();
//    for(;;)
//      ;
  }

  delay(5000);
}


boolean cosm(String data){
  if (client.open("api.pachube.com", 80)) {
    Serial.println("connected to cosm...");
    for (int i=0;i<(sizeof(cosm_table)/sizeof(int));i++){    
      client.println(strcpy_P(buffer, (char*)pgm_read_word(&(cosm_table[i]))));
    }

    client.print("Content-Length: "); 
    client.println(data.length());
    client.println();
    client.println(data);
    client.println();
  } 
  else {
    Serial.println("connection to cosm failed.");
  }
}

Where is buffer allocated?

Just above the setup function. Outside of the function I’m trying to pass the pstring to.

According to the above link, you need to pass buffer to Serial.Print, not postData.
