 The \fBPathCache\fR object is part of the \fBlibtecla\fR(3LIB) library.
 \fBPathCache\fR objects allow an application to search for files in any colon
 separated list of directories, such as the UNIX execution \fBPATH\fR
 environment variable. Files in absolute directories are cached in a
 \fBPathCache\fR object, whereas relative directories are scanned as needed.

 .SS "Function Descriptions"
-.sp
-.LP
 To use the facilities of this module, you must first allocate a \fBPathCache\fR
 object by calling the \fBnew_PathCache()\fR constructor function. This function
 creates the resources needed to cache and lookup files in a list of
 directories. It returns \fINULL\fR on error.
 .SS "Populating The Cache"
-.sp
-.LP
 Once you have created a cache, it needs to be populated with files. To do this,
 call the \fBpca_scan_path()\fR function. Whenever this function is called, it
 discards the current contents of the cache, then scans the list of directories
 specified in its path argument for files. The path argument must be a string
 containing a colon-separated list of directories, such as

 If you are only interested in certain types or files, such as, for example,
 executable files, or files whose names end in a particular suffix, you can
 arrange for the file completion and lookup functions to be selective in the
 filenames that they return. This is done by registering a callback function

-.LP
 If \fBpca_scan_path()\fR reports that an error occurred by returning 1, you can
 obtain a terse description of the error by calling
 \fBpca_last_error\fR(\fIpc\fR). This returns an internal string containing an
 error message.

 Once you have finished using a \fBPathCache\fR object, you can reclaim its
 resources by passing it to the \fBdel_PathCache()\fR destructor function. This

 It is safe to use the facilities of this module in multiple threads, provided
 that each thread uses a separately allocated \fBPathCache\fR object. In other
 words, if two threads want to do path searching, they should each call
 \fBnew_PathCache()\fR to allocate their own caches.
