Detailed Description

Deprecated:
Erase a file in a way that makes recovery impossible -- well, no guarentee of that, but at least as difficult as reasonably possible.

For this, KShred write several times over the existing file, using different patterns, before deleting it.

true on success, false on error (invalid filename or write error)

Definition at line 75 of file kshred.cpp.

bool KShred::fill1s ( )

Writes all 1's over the entire file and flushes the file buffers.

Returns:
true on success, false on error (invalid filename or write error)

Definition at line 68 of file kshred.cpp.

bool KShred::fillbyte ( unsigned int  byte)

Writes the specified byte over the entire file and flushes the file buffers.

Parameters:
bytethe value to write over every byte of the file
Returns:
true on success, false on error (invalid filename or write error)

Definition at line 82 of file kshred.cpp.

bool KShred::fillpattern ( unsigned char *  pattern,
unsigned int  size 
)

Writes the specified byte array over the entire file and flushes the file buffers.

Parameters:
patternthe value to write over the entire file
sizethe length of the 'pattern' byte array
Returns:
true on success, false on error (invalid filename or write error)

Definition at line 103 of file kshred.cpp.

bool KShred::fillrandom ( )

Writes random bites over the entire file and flushes the file buffers.

Definition at line 122 of file kshred.cpp.

void KShred::infoMessage ( const TQString &  message) [signal]

Shows a message in the progress dialog.

Parameters:
messagethe message to display
void KShred::processedSize ( TDEIO::filesize_t  bytes) [signal]

Shows progress of the shredding.

Parameters:
bytesthe number of bytes written to the file
bool KShred::shred ( )

Shreds a file by writing a series of values over it (uses fill0s, then fill1s, then fillrandom, then fillbyte with 0101..., then fillbyte with 1010....

Returns:
true on success, false on error (invalid filename or write error)

Definition at line 207 of file kshred.cpp.
