call "CBL_ALLOC_DYN_MEM" using mem-pointer by value mem-size flags returning status-code
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 |
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. |
0 | Successful allocation |
157 | Unable to allocate memory |
181 | Contradictory flags specification |
Comments:
The memory allocated is not initialized to any value.
The maximum size of this allocated memory is restricted only by your operating system (unless the -l run-time switch is set).
If bit 2 is not set the memory allocated by CBL_ALLOC_DYN_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 run unit terminates, if it has not been previously freed by CBL_FREE_DYN_MEM.
