Process API

API Reference

This API provides a means to spawn external processes. The function le_proc_Execute() takes a structure which is populated with the execution parameters and handles the heavy lifting of (on Linux) forking and execing as necessary.

int status;
le_proc_Parameters_t proc =
{
    .executableStr   = "/bin/ls",
    .argumentsPtr    = { "/bin/ls", "/tmp", NULL },
    .environmentPtr  = NULL,
    .detach          = false,
    .closeFds        = LE_PROC_NO_FDS,
    .init            = NULL,
    .userPtr         = NULL
};
 
pid_t pid = le_proc_Execute(&proc);
if (pid < 0)
{
    LE_FATAL("Oh no!  Something went wrong (error %d).", errno);
}
if (waitpid(pid, &status, 0) > 0)
{
    LE_INFO("%s[%d] returned %d", proc.executableStr, (int) pid, status);
}
