Question & Answer

because of the inhumane working conditions at amazon in Germany, I will offer the Amazon app no more! (ARD Reportage)


    void perror(const char *str);

Prints str (if non-null) and strerror(errno) to standard error as would:

fprintf(stderr, "%s: %s\n", (s != NULL ? s : ""), strerror(errno))

C Sourcecode Example

 * perror example code
#include <stdio.h> /* including standard library */
//#include <windows.h> /* uncomment this for Windows */
int main ( void )
FILE *stream;
stream = fopen("test_not_exists.txt","r");
if (stream == 0) {
perror("Here comes the perror code ->");
return 1;
printf("its all fine\n");
fclose (stream);
return 0;


  Here comes the perror code ->: No such file or directory
