Description:
This
function converts a supplied string to upper or lower case, storing the result in a
supplied buffer. The
astStringCase function is similar, but stores the result
in a dynamically allocated buffer.
Synopsis
void astChrCase( const char
in, char
out, int upper, int
blen, int status
)
Parameters:
in
Pointer to the null terminated string to be converted. If this
is NULL, the supplied contents of the "
out"
string are used as the input string.
out
Pointer to the buffer to receive the converted string. The length of this
buffer is given by "
blen"
. If NULL is supplied for "
in"
, then the supplied
contents of "
out"
are converted and written back into "
out"
over-writing the
supplied contents.
upper
If non-zero, the string is converted to upper case.
Otherwise it is converted to lower case.
blen
The length of the output buffer.
Ignored if "
in"
is NULL. No more than "
blen - 1"
characters will be copied
from "
in"
to "
out"
, and a terminating null character will then be added.
