# Process API

- [API reference](https://docs.qualcomm.com/doc/80-41102-2/topic/_doxygen_rst_file__doxygen_sources_include_le_process_h.html#file-le-process-h)

This API provides a means to spawn external processes. The function [le\_proc\_Execute()](https://docs.qualcomm.com/doc/80-41102-2/topic/function_a00095_1a75b0bc4101d9c6eb62f9bf9a7ffb6b71.html#Documentationa00095_1a75b0bc4101d9c6eb62f9bf9a7ffb6b71) 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);
    }
