Function
GLibChecksumnew
since: 2.16
Declaration [src]
GChecksum*
g_checksum_new (
GChecksumType checksum_type
)
Description [src]
Creates a new GChecksum, using the checksum algorithm checksum_type.
If the checksum_type is not known, NULL is returned. A GChecksum can be used to compute the checksum, or digest, of an
arbitrary binary blob, using different hashing algorithms.
A GChecksum works by feeding a binary blob through g_checksum_update()
until there is data to be checked; the digest can then be extracted
using g_checksum_get_string(), which will return the checksum as a
hexadecimal string; or g_checksum_get_digest(), which will return a
vector of raw bytes. Once either g_checksum_get_string() or
g_checksum_get_digest() have been called on a GChecksum, the checksum
will be closed and it won’t be possible to call g_checksum_update()
on it anymore.
Available since: 2.16
Parameters
checksum_type-
Type:
GChecksumTypeThe desired type of checksum.
Return value
Type: GChecksum
The newly created GChecksum, or NULL. Use g_checksum_free() to free the memory allocated by it.
| The caller of the function takes ownership of the data, and is responsible for freeing it. |
The return value can be NULL. |
