Function Stream system initialization

Function name STM_Init

No 1.1

Format

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

input

grp_open_max	: Maximum number of stream groups that can be opened at the same time (from 1 to 24)
stm_open_max	: Maximum number of streams to open simultaneously (1 to 24)
work	:Work area

output

none

function value

TRUE	: If initialization was successful
FALSE	: If the initialization cannot be performed normally.

function

Immediately after the program starts, it initializes to use the stream system.

remarks

1. It must be done immediately after GFS_Init.
   The maximum number of files that can be opened simultaneously (open_max) specified in GFS_Init must be greater than or equal to stm_open_max.
2. The size of the work area is determined by STM_WORK_SIZE(grp_open_max, stm_open_max) bytes. Place work on a 4-byte boundary.
