Function
FwupdPluginmemread_uint24_safe
since: 1.8.3
Declaration [src]
gboolean
fu_memread_uint24_safe (
const guint8* buf,
gsize bufsz,
gsize offset,
guint32* value,
FuEndianType endian,
GError** error
)
Description [src]
Read a value from a buffer using a specified endian in a safe way.
You don’t need to use this function in “obviously correct” cases, nor should you use it when performance is a concern. Only us it when you’re not sure if malicious data from a device or firmware could cause memory corruption.
Available since: 1.8.3
Parameters
buf-
Type:
const guint8*Source buffer.
The data is owned by the caller of the function. bufsz-
Type:
gsizeMaximum size of
buf, typicallysizeof(buf). offset-
Type:
gsizeOffset in bytes into
bufto copy from. value-
Type:
guint32*The parsed value.
The argument will be set by the function. The argument can be set to NULLby the function. endian-
Type:
FuEndianTypeAn endian type, e.g.
G_LITTLE_ENDIAN. error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the function if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
