#include <sys/types.h>
#include <regex.h>

#include <stdio.h>
#include <string.h>

main ()
{
    regex_t preg;
    regmatch_t pmatch[1];
    int a, b;
    char *test;

    if (regcomp (&preg, "\\w+", REG_EXTENDED) != 0) {
	puts ("error in regcomp()");
	exit (1);
    }
    test = "abc_123";
    if (regexec (&preg, test, 1, pmatch, 0) != 0) {
	puts ("error in regexec()");
	exit (2);
    }
    a = pmatch[0].rm_so;
    b = pmatch[0].rm_eo;
    printf ("-- test={%s}, match={%s}\n", test, strndup (test + a, b - a));
    regfree (&preg);
}

$ cc test.c -o test
$ ./test
-- test={abc_123}, match={abc_}

What I expected is
-- test={abc_123}, match={abc_123}
