Macro Definition Documentation

◆ _GK_ERROR_C_

#define _GK_ERROR_C_
Value:
/* this is needed to properly declare the gk_jub* variables
as an extern function in GKlib.h */

Definition at line 13 of file error.c.

◆ MAX_JBUFS

#define MAX_JBUFS   128

Definition at line 21 of file error.c.

Typedef Documentation

◆ gksighandler_t

typedef void(* gksighandler_t) (int)

Definition at line 26 of file error.c.

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.

◆ gk_NonLocalExit_Handler()

void gk_NonLocalExit_Handler ( 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 ( int  signum)

This function is the custome signal handler, which all it does is to perform a longjump to the most recent saved environment

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()

Definition at line 175 of file error.c.
