LZDone

3.1

The LZDone function frees buffers that the LZStart function allocated for multiple-file copy operations.

Parameters

This function has no parameters.

Return Value

This function does not return a value.

Comments

Applications that copy multiple files should call LZStart before copying the files with the CopyLZFile function. LZStart allocates buffers for the file copy operations.

Example

The following example uses LZDone to free buffers allocated by LZStart:

#define NUM_FILES   4

char *szSrc[NUM_FILES] =
    {"readme.txt", "data.txt", "update.txt", "list.txt"};
char *szDest[NUM_FILES] =
    {"readme.bak", "data.bak", "update.bak", "list.bak"};
OFSTRUCT ofStrSrc;
OFSTRUCT ofStrDest;
HFILE hfSrcFile, hfDstFile;
int i;

/* Allocate internal buffers for the CopyLZFile function. */

LZStart();

/* Open, copy, and then close the files. */

for (i = 0; i < NUM_FILES; i++) {
    hfSrcFile = LZOpenFile(szSrc[i], &ofStrSrc, OF_READ);
    hfDstFile = LZOpenFile(szDest[i], &ofStrDest, OF_CREATE);
    CopyLZFile(hfSrcFile, hfDstFile);
    LZClose(hfSrcFile);
    LZClose(hfDstFile);
}

LZDone(); /* free the internal buffers */
