NAME
     dwarf_srcfiles -- retrieve source file information

LIBRARY
     DWARF Access Library (libdwarf, -ldwarf)

SYNOPSIS
     #include <libdwarf.h>

     int
     dwarf_srcfiles(Dwarf_Die die, char ***filenames, Dwarf_Signed *filenamecount, Dwarf_Error *err);

DESCRIPTION
     Function dwarf_srcfiles() returns the source file names associated with a compilation unit.  Source file names are returned as an array of
     NUL-terminated strings.

     Argument die should reference a DWARF debugging information entry descriptor with source file information, see dwarf(3).  Argument filenames
     should point to a location that will hold a pointer to the returned array of file names.  Argument filenamecount should point to a location
     that will hold the number of file names returned.	If argument err is not NULL, it will be used to store error information in case of an
     error.

   Memory Management
     The memory areas used for the file names and for array of pointers being returned are managed by the DWARF(3) library.  The application
     should not attempt to directly free these memory areas.  Portable code should indicate that the memory areas are to be freed by using
     dwarf_dealloc(3).

RETURN VALUES
     Function dwarf_srcfiles() returns DW_DLV_OK when it succeeds.  In case of an error, it returns DW_DLV_ERROR and sets the argument err.

ERRORS
     Function dwarf_srcfiles() can fail with:

     [DW_DLE_ARGUMENT]	One of the arguments die, filenames or filenamecount was NULL.

     [DW_DLE_NO_ENTRY]	The compilation unit referenced by argument die does not have associated source file information.

     [DW_DLE_MEMORY]	An out of memory condition was encountered during the execution of this function.
