Thread-topic: execve errno setting on MIPS
Hi all,
Please find the below testcase..
#include <stdio.h>
#include <limits.h>
#include <errno.h>
#include <unistd.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#define EXE_NAME "./exe"
char e2BIG[ARG_MAX+1][10];
char *envList[]={NULL};
int main(void)
  int ret,ind;
  for(ind = 0; ind < ARG_MAX+1; ind++)
    strcpy(e2BIG[ind], "helloword");
  if ((ret = chmod(EXE_NAME,0744)) != 0){
    printf("chmod failed\n");
  /* whne arg list is too long */
  if ((ret = execve(EXE_NAME,e2BIG,envList)) == -1) {
    if ( errno == E2BIG)
      printf("Test Pass\n");
      printf("Test Fail : Got Errno %d\n", errno);
    printf("execve worked out of limit\n");
On MIPS E2BIG is not getting set as errno instead EFAULT is set, while on 
other archs like ARM, PowerPC and i686 I am able to get E2BIG.
Please let me know about the issue...
Let EXE_NAME be any executable....
