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.

Function Documentation

char* lr_checksum_fd ( LrChecksumType  type,
int  fd,
GError **  err 
)

Calculate checksum for data pointed by file descriptor.

Parameters
typeChecksum type
fdOpened file descriptor. Function seeks to the begin of the file.
errGError **
Returns
Malloced checksum string or NULL on error.
gboolean lr_checksum_fd_cmp ( LrChecksumType  type,
int  fd,
const char *  expected,
gboolean  caching,
gboolean *  matches,
GError **  err 
)

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

Parameters
typeChecksum type
fdFile descriptor
expectedString with expected checksum value
cachingCache/Use cached checksum value as extended file attr.
matchesSet pointed variable to TRUE if checksum matches.
errGError **
Returns
returns TRUE if error is not set and FALSE if it is
LrChecksumType lr_checksum_type ( const char *  type)

Convert checksum name (string) to LrChecksumType.

Parameters
typeString 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
typeChecksum type
Returns
Constant string with name of the checksum
