The LZSeek function moves a file pointer a number of bytes from a starting position.
LONG LZSeek(
INT hFile, |
// handle of source file |
LONG lOffset, |
// number of bytes to move |
INT iOrigin |
// starting position |
); |
Value |
Meaning |
0 |
Moves the file pointer lOffset bytes from the beginning of the file. |
1 |
Moves the file pointer lOffset bytes from the current position. |
2 |
Moves the file pointer lOffset bytes from the end of the file. |
If the function succeeds, the return value specifies the offset from the beginning of the file to the new pointer position.
If the function fails, the return value is an LZERROR_* code. These codes have values less than zero. Note that LZSeek calls neither SetLastError nor SetLastErrorEx; thus, its failure does not affect a thread’s last-error code.
Upon failure, LZSeek can return the following LZERROR_* codes:
Value |
Meaning |
LZERROR_BADINHANDLE |
The handle identifying the source file is not valid. The file cannot be read. |
LZERROR_BADVALUE |
One of the parameters is outside the range of acceptable values. |
LZERROR_GLOBLOCK |
The LZ file handle cannot be locked down. |
There is no extended error information for this function; do not call GetLastError.
The handle identified by the hFile parameter must be retrieved by calling either the LZInit or LZOpenFile function.
If the file is compressed, LZSeek emulates the _llseek function on an expanded image of the file.
