CBL_ALLOC_THREAD_MEM

Allocates thread-specific heap memory.

Syntax:

call "CBL_ALLOC_THREAD_MEM" using      mem-pointer
                            by value  mem-size
                            by value  flags
                            returning status-code

Parameters:

	Using call prototype (see Key)	Picture
`mem-pointer`	cblt-pointer	usage pointer. Must be level 01.
`mem-size`	cblt-os-size	pic x(4) comp-5 or pic x(8) comp-5 (64-bit native programs only)
`flags`	cblt-os-flags	pic x(4) comp-5 or pic x(8) comp-5 (64-bit native programs only)
`status-code`	See Library Routines - Key

On Entry:

mem-size

The number of bytes of memory to allocate.

flags

Bits 0-1	Reserved. Must be set to 0.
Bit 2	Allocate this memory independently from any calling program.
Remaining bits	Reserved. Must be set to 0.

On Exit:

mem-pointer

A pointer to the memory allocated. The allocated memory is not initialized.

status-code

0	Successful allocation
157	Unable to allocate memory
181	Contradictory `flags` specification

Coments:

If bit 2 is not set the memory allocated by CBL_ALLOC_THREAD_MEM is freed when the program that allocated it is canceled (logically or physically), if there is a COBOL program that is directly or indirectly the caller.

If bit 2 is set, this memory is freed when the thread that allocated it terminates, if it has not been previously freed by CBL_FREE_THREAD_MEM.
