|
* Name: insmod
|
|
*
|
|
* Description:
|
|
* Verify that the file is an ELF module binary and, if so, load the
|
|
* module into kernel memory and initialize it for use.
|
|
*
|
|
* NOTE: modlib_setsymtab() had to have been called in board-specific OS
|
|
* logic prior to calling this function from application logic (perhaps via
|
|
* boardctl(BOARDIOC_OS_SYMTAB). Otherwise, insmod will be unable to
|
|
* resolve symbols in the OS module.
|
|
*
|
|
* Input Parameters:
|
|
*
|
|
* filename - Full path to the module binary to be loaded
|
|
* modname - The name that can be used to refer to the module after
|
|
* it has been loaded.
|
|
*
|
|
* Returned Value:
|
|
* A non-NULL module handle that can be used on subsequent calls to other
|
|
* module interfaces is returned on success. If insmod() was unable to
|
|
* load the module insmod() will return a NULL handle and the errno
|
|
* variable will be set appropriately.
