OpenersNotesSection(Spacer1)Details

MLUTF8LinkName() allocates memory for the link name string that must be released. To release the memory, call (NonWLLink[MLReleaseUTF8LinkName(), paclet:/ref/c/MLReleaseUTF8LinkName]) on the value returned by the function. If MLUTF8LinkName() returns NULL, do not call (NonWLLink[MLReleaseUTF8LinkName(), paclet:/ref/c/MLReleaseUTF8LinkName]) on the NULL value.

Programs should not modify the contents of the string returned by MLUTF8LinkName().

MathLink links are created using a combination of link mode, link protocol, and other options. The link name provides necessary information for the link mode and link protocol used to create the link.

MLUTF8LinkName() is declared in the MathLink header file (RefLink[mathlink.h, paclet:/ref/file/mathlink.h]).
