BOOTSTRAP (kutils) functions


LIBRARY ROUTINE

kstring_lower - convert a string to lower case.

LIBRARY CALL

char *kstring_lower(
   const char *istr,
   char       *ostr)

INPUT

OUTPUT

RETURN VALUE

The converted string, 'ostr' if that variable is not NULL, or a pointer to the resulting allocated string. NULL is returned on an allocation error or if 'istr' is NULL.

DESCRIPTION

This routine performs a character by character scan for uppercase characters. When an uppercase character is found, it calls the function tolower() to get the lowercase equivalent, and replaces it.

Note that if 'ostr' is non-NULL, the calling routine must ensure that 'ostr' points to a memory buffer large enough to hold the converted string plus a null character. If the buffer is not large enough, memory will be overwritten resulting in unpredicable program failure.
