mod_install(9F) Kernel Functions for Drivers mod_install(9F) NAME
mod_install, mod_remove, mod_info - add, remove or query a loadable module SYNOPSIS
#include <sys/modctl.h> int mod_install(struct modlinkage *modlinkage); int mod_remove(struct modlinkage *modlinkage); int mod_info(struct modlinkage *modlinkage, struct modinfo *modinfo); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
modlinkage Pointer to the loadable module's modlinkage structure which describes what type(s) of module elements are included in this loadable module. modinfo Pointer to the modinfo structure passed to _info(9E). DESCRIPTION
mod_install() must be called from a module's _init(9E) routine. mod_remove() must be called from a module's _fini(9E) routine. mod_info() must be called from a module's _info(9E) routine. When _init(9E) is executing, its call to mod_install() enables other threads to call attach(9E) even prior to mod_install() returning and _init(9E) completion. From a programming standpoint this means that all _init(9E) initialization must occur prior to _init(9E) calling mod_install(). If mod_install() fails (non-zero return value), any initialization must be undone. When _fini(9E) is executing, another thread may call attach(9E) prior to _fini(9E) calling mod_remove(). If this occurs, the mod_remove() fails (non-zero return). From a programming standpoint, this means that _init(9E) initilizations should only be undone after a successful return from mod_remove(). RETURN VALUES
mod_install() and mod_remove() return 0 upon success and non-zero on failure. mod_info() returns a non-zero value on success and 0 upon failure. EXAMPLES
See _init(9E) for an example that uses these functions. SEE ALSO
