* is a fixed size array of struct symtab_s. The information is intentionally
|

|
|
* minimal and supports only:
|
||
|
|
*
|
||
|
|
* 1. Function pointers as sym_values. Of other kinds of values need to be
|

|
|
* supported, then typing information would also need to be included in
|
||
|
|
* the structure.
|
||
|
|
*
|
||
|
|
* 2. Fixed size arrays. There is no explicit provisional for dynamically
|
||
|
|
* adding or removing entries from the symbol table (realloc might be
|
||
|
|
* used for that purpose if needed). The intention is to support only
|
||
|
|
* fixed size arrays completely defined at compilation or link time.
