Function
Gioresources_lookup_data
since: 2.32
Declaration
GBytes*
g_resources_lookup_data (
const char* path,
GResourceLookupFlags lookup_flags,
GError** error
)
Description
Looks for a file at the specified path in the set of
globally registered resources and returns a GBytes that
lets you directly access the data in memory.
The data is always followed by a zero byte, so you can safely use the data as a C string. However, that byte is not included in the size of the GBytes.
For uncompressed resource files this is a pointer directly into the resource bundle, which is typically in some readonly data section in the program binary. For compressed files we allocate memory on the heap and automatically uncompress the data.
lookup_flags controls the behaviour of the lookup.
Available since: 2.32
Parameters
path-
Type:
const char*A pathname inside the resource.
The data is owned by the caller of the function. The value is a NUL terminated UTF-8 string. lookup_flags-
Type:
GResourceLookupFlagsA
GResourceLookupFlags. 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 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.
Return value
Type: GBytes
GBytes or NULL on error.
Free the returned object with g_bytes_unref()
