Function Documentation

errexit()

void errexit	(	char *	f_str,
			...
	)

This function prints an error message and exits

Definition at line 54 of file error.c.

gk_errexit()

void gk_errexit	(	int	signum,
		char *	f_str,
			...
	)

This function prints an error message and raises a signum signal

Definition at line 77 of file error.c.

int

signum

)

Definition at line 166 of file error.c.

gk_set_exit_on_error()

void gk_set_exit_on_error

(

int

value

This function sets the gk_exit_on_error variable

Definition at line 43 of file error.c.

gk_SetSignalHandlers()

void gk_SetSignalHandlers

(

)

Definition at line 145 of file error.c.

gk_sigthrow()

void gk_sigthrow

(

Definition at line 135 of file error.c.

gk_sigtrap()

int gk_sigtrap

(

)

This function sets a number of signal handlers and sets the return point of a longjmp

Definition at line 98 of file error.c.

gk_siguntrap()

int gk_siguntrap

(

)

This function sets the handlers for the signals to their default handlers

Definition at line 116 of file error.c.

gk_strerror()

char* gk_strerror

(

int

errnum

)

Thread-safe implementation of strerror()
