Maybe something like this using brackets to group commands together...
If command1 is successful, then run the 'dostuff' function, if not successful, print error message.
if you're calling a function though, you don't need the parentheses, as in "dostuff()", it would just be "dostuff". You can use the parentheses when you're defining a function though.

elf_errno
elf_errmsg(3ELF) ELF Library Functions elf_errmsg(3ELF)NAME
elf_errmsg, elf_errno - error handling
SYNOPSIS
cc [ flag ... ] file ... -lelf [ library ... ]
#include <libelf.h>
const char *elf_errmsg(int err);
int elf_errno(void);
DESCRIPTION
If an ELF library function fails, a program can call elf_errno() to retrieve the library's internal error number. As a side effect, this
function resets the internal error number to 0, which indicates no error.
The elf_errmsg() function takes an error number, err, and returns a null-terminated error message (with no trailing new-line) that
describes the problem. A zero err retrieves a message for the most recent error. If no error has occurred, the return value is a null
pointer (not a pointer to the null string). Using err of -1 also retrieves the most recent error, except it guarantees a non-null return
value, even when no error has occurred. If no message is available for the given number, elf_errmsg() returns a pointer to an appropriate
message. This function does not have the side effect of clearing the internal error number.
EXAMPLES
Example 1: A sample program of calling the elf_errmsg() function.
The following fragment clears the internal error number and checks it later for errors. Unless an error occurs after the first call to
elf_errno(), the next call will return 0.
(void)elf_errno();
/* processing ... */
while (more_to_do)
{
if ((err = elf_errno()) != 0)
{
/* print msg */
msg = elf_errmsg(err);
}
}
