◆ _sceFiosKernelOverlayGetRecommendedScheduler()

int _sceFiosKernelOverlayGetRecommendedScheduler ( int  scheduler_count,
const char *  partially_resolved_path,
SceUInt64 *  args 
)

Gets the recommended scheduler index for a partially resolved path.

Parameters
[in]scheduler_count- Number of available schedulers.
[in]partially_resolved_path- Optional partially resolved path.
[in]args- Non-NULL pointer to an 8-byte block. Its contents are unused on FW 3.60. Still declared as a SceUInt64 pointer for backwards compatibility; points to a SceFiosGetRecommendedSchedulerSyscallArgs structure.
Returns
1 for a host[0-9]: path when scheduler_count is greater than 1, otherwise 0, or a negative error code when a user-memory copy fails.

◆ _sceFiosKernelOverlayResolveSync()

int _sceFiosKernelOverlayResolveSync ( SceUID  pid,
int  resolve_for_write,
const char *  in_path,
SceFiosResolveSyncSyscallArgs *  args 
)

Resolves a path synchronously through a process's overlays.

args must be non-NULL. Its max_path field controls input validation and path resolution, while out_path_buffer_size independently controls the final copy to user memory. The reserved fields are ignored on FW 3.60.

Parameters
[in]pid- Process whose overlays are used.
[in]resolve_for_write- Must be 0 for read resolution or 1 for write resolution.
[in]in_path- Path to resolve.
[in,out]args- Resolution options and output buffer.
Returns
0 on success, or a negative error code.

◆ VITASDK_BUILD_ASSERT_EQ() [6/6]

VITASDK_BUILD_ASSERT_EQ ( 0x18  ,
SceFiosResolveWithRangeSyncSyscallArgs

◆ _sceFiosKernelOverlayResolveWithRangeSync()

int _sceFiosKernelOverlayResolveWithRangeSync ( SceUID  pid,
int  resolve_for_write,
const char *  in_path,
SceFiosResolveWithRangeSyncSyscallArgs *  args 
)

Resolves a path through overlays whose order is between min_order and max_order, inclusive.

args must be non-NULL. min_order and max_order are unsigned, and min_order must not exceed max_order. max_path controls path validation and resolution; out_path_buffer_size independently controls the final copy to user memory. The reserved fields are ignored on FW 3.60. If application overlays are disabled for the current thread, the supplied min_order is replaced with 0x80.

Parameters
[in]pid- Process whose overlays are used.
[in]resolve_for_write- Must be 0 for read resolution or 1 for write resolution.
[in]in_path- Path to resolve.
[in,out]args- Resolution options and output buffer.
Returns
0 on success, or an error code.
