    NAME

    
    
    abort2
    
     - abort process with diagnostics
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <stdlib.h>
    void abort2 (const char *why int nargs void **args);
     

    DESCRIPTION

    The abort2 ();
    system call causes the process to be killed and the specified diagnostic message (with arguments) to be delivered by the kernel to the syslogd(8) daemon.

    The Fa why argument points to a NUL- terminated string specifying a reason of the program's termination (maximum 128 characters long). The Fa args array contains pointers which will be logged numerically (with the kernel's `%p' printf(9) format). The Fa nargs argument specifies the number of pointers in Fa args (maximum 16).

    The abort2 ();
    system call is intended for use in situations where continuation of a process is impossible or for other definitive reasons is unwanted, and normal diagnostic channels cannot be trusted to deliver the message.  

    RETURN VALUES

    The abort2 ();
    function never returns.

    The process is killed with SIGABRT unless the arguments to abort2 ();
    are invalid, in which case SIGKILL is used.  

    EXAMPLES

    #include <stdlib.h>
    
    if (weight_kg > max_load) {
            void *ptrs[3];
    
            ptrs[0] = (void *)(intptr_t)weight_kg;
            ptrs[1] = (void *)(intptr_t)max_load;
            ptrs[2] = haystack;
            abort2("Camel overloaded", 3, ptrs);
    }
