perror question

[Clunixchit]

Im writing a program in which i have to perform several mallocs

in order to simply my code i have used
void e_malloc(){
perror("malloc");
_exit(EXIT_FAILURE);
}

if ( !(phrase.T = malloc ( sizeof *(phrase.T)
)))
e_malloc();
instead of
[code:1:c9ebbe2331]if ( !(phrase.T = malloc ( sizeof
*(phrase.T) ))) {
perror("malloc");
_exit(EXIT_FAILURE);
}[/code:1:c9ebbe2331]
my question is, does perror wld still contain the errno message if the
malloc fails

errno is a global variable (or looks like a global variable). If set by
malloc it will have the same value in all other functions that reference
it until set to a new value. It won't be changed by simply calling another
function.

perror() references the current value of errno.
