* Name: symtab_findbyvalue
|
|
*
|
|
* Description:
|
|
* Find the symbol in the symbol table whose value closest (but not greater
|
|
* than), the provided value. This version assumes that table is not
|
|
* ordered with respect to symbol name and, hence, access time will be
|
|
* linear with respect to nsyms.
|
|
*
|
|
* Returned Value:
|
|
* A reference to the symbol table entry if an entry with the matching
|
|
* name is found; NULL is returned if the entry is not found.
