Porting from Linux

Hi

I m porting C code from Linux to symbian. Can somebody advise me how should i handle CHAR and INT's.

Im getting below errors:
expression syntax error Char or Int
undefined identifier Char ot Int

Char example code:

  char *publickeybuf = NULL;
  long publickeylength = 0;
 
  x = CM_writePublicKeyString(key, &publickeybuf, &publickeylength);

Int Example:

int row_count = aa_dbResultSetGetRowCount(&rs);
 
  if (row_count > 0)
  {
    char **ca_list;
   
    if ((ca_list = (char **)malloc(row_count * sizeof(char *))) == NULL)
    {
      SESSI_LOG("%s \n", "Memory allocation failed" );
      return AA_ERR_MEMORY_ALLOCATION_FAILED;
    }
   
    int i;
    for (i = 0; i < row_count; i++)

Thanks
Capr
