GETPROGNAME(3)             BSD Programmer's Manual              GETPROGNAME(3)


     getprogname, setprogname - get/set the name of the current program


     #include <stdlib.h>

     const char *

     setprogname(const char *name);


     These utility functions get and set the current program's name as used by
     various error-reporting functions.

     getprogname() returns the name of the current program. This function is
     typically useful when generating error messages or other diagnostic out-

     The setprogname() function sets the name of the program to be the last
     path component of the name argument. Internally, only the pointer to the
     given string is kept as the program name, so it should not be modified
     and the storage for the string must remain valid for the rest of the
     program's lifetime.

     The getprogname() and setprogname() functions first appeared in
     OpenBSD 5.4 as function-based wrappers around the 4.4BSD __progname in-


     The string returned by getprogname() is supplied by the invoking process
     and should not be trusted by setuid or setgid programs.
