CYGPKG_UITRON_MEMPOOLVAR
Boolean
uITRON supports memory pools for dynamic, task-safe memory allocation. Two kinds are supported, fixed-size and variable-size. There may be multiple of each type of pool, each with differing characteristics. This option controls whether there are any variable-size memorypools in the system. A variable-size memorypool allocates blocks of memory of any size requested, resources permitting.
CYGNUM_UITRON_MEMPOOLVAR
Count
The number of uITRON Variable-Size Memorypools present in the system. Valid Variable-Size Memorypool IDs will range from 1 to this value.
CYGPKG_UITRON_MEMPOOLVAR_CREATE_DELETE
Boolean
Support variable-size memory pool create and delete operations (cre_mpl, del_mpl). Otherwise all variable-size mempools are created, up to the number specified above.
CYGNUM_UITRON_MEMPOOLVAR_INITIALLY
Count
The number of variable-size mempools initially created. This number should not be more than the number of variable mempools in the system, though setting it to a large value to mean "all" is acceptable. Initially, only variable mempools numbered from 1 to this number exist; higher numbered ones must be created before use. All mempools must be initialized to tell the system what memory to use for each pool.
CYGDAT_UITRON_MEMPOOLVAR_EXTERNS
Multiline
Variable mempool initializers may refer to external objects such as memory for the pool to manage. Use this option to define or declare any external objects needed by the pool"s static initializer below. Example: create some memory for a mempool using "static char vpool1[2000];" to set up a chunk of memory of 2000 bytes. Note: this option is invoked in the "outermost" context of C++ source, where global/static objects are created; it should contain valid, self-contained, C++ source.
CYGDAT_UITRON_MEMPOOLVAR_INITIALIZERS
Multiline
Variable block memory pools should be statically initialized: enter a list of initializers separated by commas, one per line. An initializer is "CYG_UIT_MEMPOOLVAR(ADDR,SIZE)" where addr is the address of memory to manage, and size is the total size of that memory. If create and delete operations are supported, initializers of the form "CYG_UIT_MEMPOOLVAR_NOEXS(ADDR,SIZE)" should be used for pools which are not initially created, to tell the system what memory to use for each pool. Note: this option is invoked in the context of a C++ array initializer, between curly brackets. Ensure that the number of initializers here exactly matches the total number of variable pools specified.
