wfdbfile

 
char *wfdbfile(char *type, char *record)
Return:

(char *)
pointer to a filename, or NULL

This function attempts to locate an existing WFDB file by searching the database path (see section 1.4 The Database Path and Other Environment Variables). Normally, the file is specified by its type (e.g., `hea', or an annotator name such as `atr') and by the record to which it belongs. A file that does not include a record name as part of its name can be found by wfdbfile if the name is passed in the type variable and record is NULL. The string returned by wfdbfile includes the appropriate component of the database path; since the database path may include empty or non-absolute components, the string is not necessarily an absolute pathname. If the WFDB library has been compiled with NETFILES support, and the WFDB path includes one or more URL prefixes, the string returned may be a URL rather than a pathname. If the file cannot be found, wfdbfile returns NULL. (This function was first introduced in WFDB library version 4.3.)
