VARIABLE I/O DESCRIPTION
-------- --- --------------------------------------------------
in I Input string.
lenout I Maximum length of output string.
out O Output string, all uppercase.
- Detailed_Input
in is the input string.
lenout is the maximum allowed length of the output string,
including the terminating null.
- Detailed_Output
out is the output string. This is the input string
with all lowercase letters converted to uppercase.
Non-letters are not affected.
If
lenout < strlen(in)+1
the output string will be truncated on the right.
A terminating null will be placed in out at position
min ( strlen(in), lenout-1 )
unless lenout is less than or equal to zero.
out may overwrite in.
- Parameters
None.
- Particulars
Convert each lowercase character in IN to uppercase.
- Examples
"This is an example" becomes "THIS IS AN EXAMPLE"
"12345 +-=? > * $ &" "12345 +-=? > * $ &"
- Restrictions
None.
- Exceptions
1) If the input string pointer is null, the error
SPICE(NULLPOINTER) will be signaled.
2) If the output string pointer is null, the error
SPICE(NULLPOINTER) will be signaled.
3) If lenout is less than or equal to zero, the error
SPICE(STRINGTOOSHORT) will be signaled.
4) If the output string is shorter than the input string, the
result will be truncated on the right.

- Version
-CSPICE Version 1.1.0, 26-JAN-2005 (NJB)
Cast to SpiceInt was applied to strlen output to suppress
compiler warnings about comparison of signed and unsigned types.
-CSPICE Version 2.0.0, 26-AUG-1999 (NJB)
Added string error checks.
-CSPICE Version 1.0.0, 08-FEB-1998 (NJB)
Based on SPICELIB Version 1.1.0, 13-MAR-1996 (KRG)
