tf_default(), sf_default()

Purpose

Gives the default path name for DP4 system files

Old names

#define _vfdefault tf_default
#define _afdefault sf_default

Syntax (CCOWN)

char* tf_default(void)
char* sf_default(void)

Syntax (DP4DBAPI)

dp4_name_string dp4_sf_default(CONN * conn,char * path_buffer,size_t buffer_size);

Description

The tf_default() and sf_default() functions get the name of the directory used to read the DP4 licence file and return a pointer to a static buffer containing this name. In the DP4DBAPI version of this API you must pass a pointer to a buffer, which should be at least 256 bytes in size. Currently the database manager does not check that the buffer is actually larget enough to hold the value, and the buffer_size parameter is ignored.

Return values

Returns a constructed pointer to the disk and path name
