Function Stream system initialization

Function Name STM_Init

No 1.1

Form

Bool STM_Init (Sint32 grp_open_max, Sint32 stm_open_max, void * work)

input

grp_open_max	: Maximum number of stream groups to open at the same time (1 to 24)
stm_open_max	: Maximum number of streams to open at the same time (1 to 24)
work	: Work area

output

none

Function value

TRUE	: When it can be initialized normally
FALSE	: When it cannot be initialized normally

function

Immediately after starting the program, it will be initialized to use the stream system.

remarks

1. Must always be done immediately after GFS_Init.
   The maximum number of files that can be opened at the same time (open_max) specified by GFS_Init should be stm_open_max or more.
2. The size of the work area is calculated by STM_WORK_SIZE (grp_open_max, stm_open_max) bytes. Place work on a 4-byte boundary.
