Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)

INTRO(1) BSD General Commands Manual INTRO(1) NAME
intro -- introduction to general commands (tools and utilities) DESCRIPTION
Section one of the manual contains most of the commands which comprise the BSD user environment. Some of the commands included in section one are text editors, command shell interpreters, searching and sorting tools, file manipulation commands, system status commands, remote file copy commands, mail commands, compilers and compiler tools, formatted output tools, and line printer commands. All commands set a status value upon exit which may be tested to see if the command completed normally. Traditionally, the value 0 signifies successful completion of the command, while a value >0 indicates an error. Some commands attempt to describe the nature of the failure by using exit codes as defined in sysexits(3), while others simply set the status to an arbitrary value >0 (typically 1). SEE ALSO
