- software signals
#include <signal.h>void(*ssignal (intsig,int (*action)(int)))(int);
intgsignal(intsig);
Thessignal() andgsignal() functions implement a software facility similar tosignal(3C).This facility is made available to users for their own purposes.
Software signals made available to users are associated with integers in theinclusive range 1 through 17. A call tossignal() associates a procedure,action, with the software signalsig; the software signal,sig, is raised bya call togsignal(). Raising a software signal causes the action establishedfor that signal to be taken.
The first argument tossignal() is a number identifying the type ofsignal for which an action is to be established. The second argumentdefines the action; it is either the name of a (user-defined)actionfunction or one of the manifest constantsSIG_DFL (default) orSIG_IGN (ignore). Thessignal() function returns the action previously established for that signal type; ifno action has been established or the signal number is illegal,ssignal()returnsSIG_DFL.
Thegsignal() raises the signal identified by its argument,sig.
If an action function has been established forsig, then that actionis reset toSIG_DFL and the action function is entered with argumentsig. Thegsignal() function returns the value returned to it by the actionfunction.
If the action forsig isSIG_IGN,gsignal() returns the value 1and takes no other action.
If the action forsig isSIG_DFL,gsignal() returns the value 0and takes no other action.
Ifsig has an illegal value or no action was ever specifiedforsig,gsignal() returns the value 0 and takes no other action.
