All of these library headers and source can be found in the github repo https://github.com/switchbrew/libnx.Aligns a block of memory with request size to bytes size. For example, a request of memalign(0x1000, 0x1001) == 0x2000 bytes allocatedMaps a memaligned block of memory from src_addr to dst_addr. The Nintendo Switch requires this call in order to make use of memory, otherwise an invalid memory access occurs.Unmaps (frees) all memory from both dst_addr and src_addr. Must be called whenever svcMapMemory is used. The Switch will expect all memory to be allocated before gfxExit() calls (<switch/gfx/gfx.h>)
