| 21 | Definition of Sunos dynamic Linking functions
|
|---|
| 22 | =============================================
|
|---|
| 23 | In order to make this implementation easier to understand here is a
|
|---|
| 24 | quick definition of the SunOS Dynamic Linking functions which are
|
|---|
| 25 | used here.
|
|---|
| 26 |
|
|---|
| 27 | dlopen
|
|---|
| 28 | ------
|
|---|
| 29 | void *
|
|---|
| 30 | dlopen(path, mode)
|
|---|
| 31 | char * path;
|
|---|
| 32 | int mode;
|
|---|
| 33 |
|
|---|
| 34 | This function takes the name of a dynamic object file and returns
|
|---|
| 35 | a descriptor which can be used by dlsym later. It returns NULL on
|
|---|
| 36 | error.
