void bmemset	(	char *	pDst,
		char	pattern,
		ushort	len

ushort bstrlen

(

char *

pString

)

POSIX strlen() look-alike. Returns length of a NULL-term'd string.

Parameters:

pString

char pointer to the NULL terminated ASCII string.

Return values:

i	The position of the last non-NULL character in the string.

00037     ushort i = 0;
00038     
00039     while (*pString++ != '\0') i++;
00040         
00041     return i;
00042 }

ushort bstrncpy	(	char *	pDst,
		char *	pSrc,
		ushort	maxn
	)

POSIX strncpy() look-alike. Copies between two strings.

Parameters:

pDst	char pointer to pre-allocated destination ASCII string.
pSrc	char pointer to NULL-terminated ASCII string to be copied.
maxn	int value specifying max. number of chars to be copied.

Return values:

i	Number of chars that were actually copied.

Warning:: Unlike the POSIX strncpy(), bstrncpy returns the no. bytes copied into the destination string.
