Parameters

 

String (PMQCHAR) – input

Null-terminated string. The null pointer is valid for the address of the String parameter, and denotes a string of zero length.

BufferLength (MQLONG) – input

Length in bytes of the buffer to receive the string padded with blanks. Must be zero or greater.

Buffer (MQCHAR × BufferLength) – output

Buffer to receive the blank-padded string. The length is given by the BufferLength parameter. If zero is specified for BufferLength, the null pointer can be specified for the address of the Buffer parameter; in all other cases, a valid (nonnull) address must be specified for the Buffer parameter.

If the number of characters preceding the first null in the String parameter is greater than the BufferLength parameter, the excess characters are omitted and MQRC_DATA_TRUNCATED results.

CompCode (MQLONG) – output

Completion code.

Reason (MQLONG) – output

Reason code qualifying CompCode.

The following reason codes indicating error and warning conditions can be returned from the mqPad call:

MQRC_BUFFER_ERROR

Buffer parameter not valid (invalid parameter address or buffer not completely accessible).

MQRC_BUFFER_LENGTH_ERROR

Buffer length not valid.

MQRC_STRING_ERROR

String parameter not valid (invalid parameter address or buffer not completely accessible).

MQRC_STRING_TRUNCATED

Data too long for output buffer and has been truncated.
