MODLOAD(8) BSD System Manager's Manual MODLOAD(8) NAME modload -- load a kernel module SYNOPSIS modload [-dquv] [-A kernel] [-e entry] [-p postinstall] [-o output_file] input_file DESCRIPTION The modload utility loads a loadable kernel module into a running system. The input file is an object file (.o file). The options to modload are as follows: -d Debug. Used to debug modload itself. -q Be very quiet. -u Delete the loaded module (output_file) after loading. If the output file was not specified, this option causes the temporary file to be kept rather than deleted. -v Print comments about the loading process. -A kernel Specify the file that is passed to the linker to resolve module references to external symbols. The symbol file must be for the currently running kernel or the module is likely to crash the system. -e entry Specify the module entry point. This is passed by modload to ld(1) when the module is linked. The default module entry point name is the module name with `_mod' appended. -p postinstall Specify the name of a shell script or program that will be exe- cuted if the module is successfully loaded. It is always passed the module id (in decimal) and module type (in hexadecimal) as the first two arguments. For loadable drivers, the third argu- ment is the block or character major device number. For a load- able system call, the third argument is the system call number. -o output_file Specify the name of the output file that is produced by the linker. If this option is not specified, a file in the /tmp di- rectory is used with the name generated from the module name with a `.out' extension. FILES /kernel default file passed to the linker to resolve ex- ternal references in the module /usr/include/sys/lkm.h file containing definitions of module types DIAGNOSTICS The modload utility exits with a status of 0 on success and with a non- zero status if an error occurs. SEE ALSO ld(1), lkm(4), modstat(8), modunload(8) HISTORY The modload command was designed to be similar in functionality to the corresponding command in SunOS 4.1.3. AUTHORS Terrence R. Lambert <terry@cs.weber.edu> BUGS The loadable device driver framework can only reserve either a character or block device entry, not both. BSD September 22, 1994 BSD
