Function
FwupdPluginbytes_get_data_safe
since: 1.6.0
Declaration [src]
const guint8*
fu_bytes_get_data_safe (
GBytes* bytes,
gsize* bufsz,
GError** error
)
Description [src]
Get the byte data in the GBytes
. This data should not be modified.
This function will always return the same pointer for a given GBytes
.
If the size of bytes
is zero, then NULL
is returned and the error
is set,
which differs in behavior to that of g_bytes_get_data().
This may be useful when calling g_mapped_file_new()
on a zero-length file.
Available since: 1.6.0
