Detailed Description

Enumeration Type Documentation

Enum of supported checksum types. NOTE! This enum guarantee to be sorted by "hash quality"

Definition at line 36 of file checksum.h.

Calculate checksum for data pointed by file descriptor.

Parameters

type	Checksum type
fd	Opened file descriptor. Function seeks to the begin of the file.
err	GError **

Calculate checksum for data pointed by file descriptor and compare it to the expected checksum value.

Parameters

type	Checksum type
fd	File descriptor
expected	String with expected checksum value
caching	Cache/Use cached checksum value as extended file attr.
matches	Set pointed variable to TRUE if checksum matches.
err	GError **

gboolean lr_checksum_fd_compare	(	LrChecksumType	type,
		int	fd,
		const char *	expected,
		gboolean	caching,
		gboolean *	matches,
		gchar **	calculated,
		GError **	err
	)

Calculate checksum for data pointed by file descriptor and compare it to the expected checksum value.

Parameters

type	Checksum type
fd	File descriptor
expected	String with expected checksum value
caching	Cache/Use cached checksum value as extended file attr.
matches	Set pointed variable to TRUE if checksum matches.
calculated	If not NULL, the calculated checksum will be pointed here, the pointed string must be freed by caller.
err	GError **

LrChecksumType lr_checksum_type ( const char * type )

Convert checksum name (string) to LrChecksumType.

Parameters

type	String with a checksum name (e.g. "sha1", "SHA256", ...)

Returns: LrChecksumType value representing the checksum or LR_CHECKSUM_UNKNOWN

const char* lr_checksum_type_to_str ( LrChecksumType type )

Convert LrChecksumType to string

Parameters

type	Checksum type
