dwarf_srcfiles —
retrieve source file information
DWARF Access Library (libdwarf, -ldwarf)
#include

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