Function g-resource-lookup-data

Lambda List

g-resource-lookup-data (resource path lookup)

Arguments

resource -- a g-resource instance
path -- a string with a pathname inside the resource
lookup -- the g-resource-lookup-flags flags

Return Value

A pointer to the data, null-pointer on error.

Details

Looks for a file at the specified path in the resource and returns a pointer 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 data.

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.

The argument lookup controls the behaviour of the lookup.
