+**============================================================================
+** The following entry points are included in this module:
+**
+**-------------------------------------------------------------------------
+**    #include <sinq_prototypes.h>
+**
+**    char *StrMatch (&str_a, &str_b, min_len)
+**	    -------
+**  Input Args:
+**	char *str_a	    - Pointer to first  string to be compared.
+**	char *str_b	    - Pointer to second string to be compared.
+**	int   min_len	    - The minimum allowed match length.
+**  Output Args:
+**	none
+**  Modified Args:
+**	none
+**  Return value:
+**	True (non-zero) if the 2 strings match.
+**  Global variables modified:
+**	none
+**  Routines called:
+**	None
+**  Description:
+**	The routine compares 2 strings, str_a and str_b, ignoring case.
+**	The length of str_a must be less than or equal to the length of str_b.
+**	The length of str_a must be at least min_len.
