54 * DESCRIPTION = Return ports supported by this port driver
55 * Currently this will return those ports this port
56 * driver supports by default.
57 * Future enhancement might be to also return any
58 * ports that have been added that now use this
59 * port driver.
60 *
61 * INPUT = hab - anchor block handle
62 * pBuf - buffer to get enumerated PORTNAMES structures
63 * cbBuf - size(in bytes) of pBuf passed in
64 *
65 * OUTPUT = *pulReturned - number of PORTNAMES structures stored in pBuf
66 * *pulTotal - total ports supported by this port driver
67 * *pcbRequired - size(in bytes) of buffer needed to store
68 * all enumerated PORTNAMES entries.
69 * pBuf - gets an array(number elements is *pulReturned) of
70 * PORTNAMES structures.
71 * Each psz in PORTNAMES structure points to a string
72 * copied into the end of pBuf.
73 *
74 * typedef struct _PORTNAMES {
75 * PSZ pszPortName; // Name of port, example: LPT1
76 * PSZ pszPortDesc; // Port description
77 * } PORTNAMES;
78 *
79 * RETURN-NORMAL = 0 - if all portnames and descriptions fit in pBuf
80 *
81 * RETURN-ERROR = ERROR_INSUFFICIENT_BUFFER - if no PORTNAMES structs
82 * could fit in buffer. Caller
83 * uses *pcbRequired to allocate
84 * a buffer big enough to store all
85 * port names.
86 * ERROR_MORE_DATA - if some, but not all, PORTNAMES structs
87 * could fit in buffer. Caller
88 * uses *pcbRequired to allocate
89 * a buffer big enough to store all
90 * port names.
91 *
92 * NOTE: early versions of the print object expected ERROR_MORE_DATA
93 * to be returned, even when no PORTNAMES structures would fit.
94 * For this reason, we do not return ERROR_INSUFFICIENT_BUFFER
