 In the descriptions here, a parameter or return value of `NULL' means
 `NULL' in the sense of the C programming language, not a MySQL `NULL'
 value.
 
 Functions that return a value generally return a pointer or an integer.
 Unless specified otherwise, functions returning a pointer return a
 non-`NULL' value to indicate success or a `NULL' value to indicate an
 error, and functions returning an integer return zero to indicate
 success or non-zero to indicate an error. Note that `non-zero' means
 just that. Unless the function description says otherwise, do not test
 against a value other than zero:
 
      if (result)                   /* correct */
          ... error ...
 
      if (result < 0)               /* incorrect */
          ... error ...
 
      if (result == -1)             /* incorrect */
          ... error ...
 
 When a function returns an error, the *Errors* subsection of the
 function description lists the possible types of errors. You can find
 out which of these occurred by calling `mysql_errno()'. A string
 representation of the error may be obtained by calling `mysql_error()'.
