Declaration [src]
GBytes*
g_resource_lookup_data (
GResource* resource,
const char* path,
GResourceLookupFlags lookup_flags,
GError** error
)
Description [src]
Looks for a file at the specified path in the resource 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 read-only data section in the program binary. For compressed files, memory is allocated on the heap and the data is automatically uncompressed.
lookup_flags controls the behaviour of the lookup.
This can return error G_RESOURCE_ERROR_NOT_FOUND if path was not found in
resource, or G_RESOURCE_ERROR_INTERNAL if decompression of a compressed
resource failed.
Available since: 2.32
Parameters
path-
Type:
const char*A path name inside the resource.
The data is owned by the caller of the method. The value is a NUL terminated UTF-8 string. lookup_flags-
Type:
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 be left initialized to NULLby the method 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.
