atsproc(3C)

NAME
     atsproc_child, atsproc_parent, atsproc_pre - add sproc pre and post
     interception routines

SYNOPSIS
     #include <unistd.h>

     int atsproc_child (void (*func)(void));

     int atsproc_parent (void (*func)(int errno,int pid));

     int atsproc_pre (void (*func)(unsigned int mask));

DESCRIPTION
     atsproc_child adds the function func to a list of functions to be called
     without arguments on entry of a child process created by sproc(2).  At
     most 32 functions may be registered by atsproc_child; the functions will
     be called in the same order as their registration.

     atsproc_parent adds the function func to a list of functions to be called
     with two integer arguments after calling sproc(2).  At most 32 functions
     may be registered by atsproc_parent; the functions will be called in the
     same order as their registration.

     atsproc_pre adds the function func to a list of functions to be called
     with one unsigned integer argument just preceeding a call to sproc(2).
     At most 32 functions may be registered by atsproc_child; the functions
     will be called in the reverse order as their registration.

     atsproc_child, atsproc_parent, and atsproc_pre all return 0 if the
     registration succeeds. Otherwise, a value of -1 is returned and errno is
     set to indicate the error.
