A monitoring interface, includes logic responsive to a pre-fork event, the pre-fork event responsive to a vfork system call. The pre-fork event includes indicia that identifies a child process to be created in accordance with the vfork system call. A method for controlling the execution of a child process created from a parent process, where the parent process is monitored by a software tool includes, receiving indicia that a vfork system call will be executed by the parent process, suspending execution of the parent process, extracting a process identifier from the indicia of the vfork system call, the process identifier corresponding to a child process to be generated by the parent process when the parent process executes the vfork system call, setting a process monitor thread to observe the child process, and resuming execution of the parent process to enable the parent process to execute past the vfork system call.

Method and apparatus for controlling execution of a child process generated by a modified parent process

A method in a computer for facilitating interaction between an application program and a subsystem is disclosed. The method includes providing a virtual process file system layer. The virtual process file system layer is configured to interact with the subsystem in a substantially content-independent manner. The method additionally includes providing a content dependent module, the content dependent module being associated with the subsystem and is configured interact with the subsystem in a content-dependent manner. The method further includes providing a directory structure table, the directory structure table being configured to track a name of the content dependent module, wherein the content-dependent module is configured to be registered with the directory structure table using a dynamic name.

Virtual process file systems and methods therefor

A method in an operating system of a computer for allowing a plurality of application programs to interact with a plurality of subsystems, at least two application programs of the plurality of application programs being associated with two different personalities. The method includes providing a plurality of modules, each of the plurality of modules being associated with at least one personality and configured to interact with one of the plurality of subsystems, at least two modules of the plurality of modules being associated with the two different personalities. The method further includes providing a process state module for tracking personality data associated with the plurality of modules, thereby allowing a first application program of the two application programs to employ a first module of the two modules to interact with a given subsystem of the plurality of subsystems, the first application program and the first module being associated with one of the two different personalities, wherein the two application programs are configured to operate concurrently.
