Data Structures
struct	SceKernelTimeval
	This struct is needed because tv_sec size is different from what newlib expect Newlib expects 64bits for seconds and PSP expects 32bits. More...
struct	_SceKernelUtilsMt19937Context
	Structure for holding a mersenne twister context. More...
struct	_SceKernelUtilsMd5Context
	Structure to hold the MD5 context. More...
struct	_SceKernelUtilsSha1Context
	Type to hold a sha1 context. More...
