* Name: symtab_findbyname
|

|
*
|
||
|
|
* Description:
|
||
|
|
* Find the symbol in the symbol table with the matching name.
|
||
|
|
* 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.
