In certain situations, the _fullpath() function may capitalize a
portion of the file specification that it returns. If _fullpath() is
called with a lowercase drive letter and an incomplete path
specification, then the returned "full" path will have an uppercase
drive letter and any portion of the full path not specified in the
call will be returned in uppercase.
If _fullpath() is called with a complete path specification, then the
path returned from the function will match the case of the argument
passed to it on a character-per-character basis. If _fullpath() is
called with a relative or partial path specification, then every part
of the path filled in by _fullpath() will be in uppercase and the
drive letter will be changed to uppercase regardless of the case used
in the argument.
The following examples demonstrate these situations. Assume that drive
D contains a subdirectory called WORK, which has a subdirectory called
TEST. In addition, assume that the TEST directory contains a file
called FILE.C and that D:\WORK\TEST is the current directory:
If _fullpath() Is
Called with the Then it Will Return
Following: the Following:
------------------ -------------------
d:\work\test\file.c d:\work\test\file.c
d:\WORK\test\FILE.C d:\WORK\test\FILE.C
file.c D:\WORK\TEST\file.c
d:file.c D:\WORK\TEST\file.c
..\test\file.c D:\WORK\test\file.c
d: D:\WORK\TEST
d:\ d:\
Notice that everything except the drive letter specified in the
argument to _fullpath() retains its case, while the information
supplied by _fullpath() is uppercase.
Microsoft has confirmed this to be a problem in C versions 6.00 and
6.00a and QuickC versions 2.50 and 2.51 (buglist2.50 and buglist2.51).
We are researching this problem and will post new information here as
it becomes available.
