| 55 | <p>The following routines are provided for client-control of

| 56 | the I/O buffers used by the library. Applications need never

| 57 | use these routines; they are provided only for
|
|---|
| 58 | ‘‘intelligent clients’’ that wish to
|
|---|
| 59 | optimize memory usage and/or eliminate potential copy
|

| 63 | <p><i>TIFFReadBufferSetup</i> sets up the data buffer used
|
|---|
| 64 | to read raw (encoded) data from a file. If the specified
|
|---|
| 65 | pointer is <small>NULL</small> (zero), then a buffer of the
|
|---|
| 66 | appropriate size is allocated. Otherwise the caller must
|
|---|
| 67 | guarantee that the buffer is large enough to hold any
|
|---|
| 68 | individual strip of raw data. <i>TIFFReadBufferSetup</i>
|
|---|
| 69 | returns a non-zero value if the setup was successful and
|
|---|
| 70 | zero otherwise.</p>

| 73 | to write raw (encoded) data to a file. If the specified

| 74 | <i>size</i> is −1 then the buffer size is selected to
|
|---|
| 75 | hold a complete tile or strip, or at least 8 kilobytes,
|
|---|
| 76 | whichever is greater. If the specified <i>buffer</i> is
|
|---|
| 77 | <small>NULL</small> (zero), then a buffer of the appropriate
|
|---|
| 78 | size is dynamically allocated. <i>TIFFWriteBufferSetup</i>
|

| 79 | returns a non-zero value if the setup was successful and
|
|---|
| 80 | zero otherwise.</p>
