DWARF_ADD_FILE_DECL(3) FreeBSD Library Functions Manual
NAME
dwarf_add_file_decl - add a source file entry to a producer instance
LIBRARY
DWARF Access Library (libdwarf, -ldwarf)
SYNOPSIS
#include <libdwarf.h>
Dwarf_Unsigned
dwarf_add_file_decl(Dwarf_P_Debug dbg, char *name, Dwarf_Unsigned dirndx,
Dwarf_Unsigned mtime, Dwarf_Unsigned size, Dwarf_Error *err);
DESCRIPTION
Function dwarf_add_file_decl() adds a source file entry to a producer
instance.
Argument dbg should reference a DWARF producer instance allocated using
dwarf_producer_init(3) or dwarf_producer_init_b(3).
Argument name should point to a NUL-terminated string containing the name
of the source file.
If the file name in argument name is not a fully qualified pathname,
argument dirndx should specify the index of the directory where the
source file resides. Otherwise, argument dirndx should be 0. Valid
directory indices are those returned by the function
dwarf_add_directory_decl(3).
Argument mtime specifies the time when the file was last modified.
Argument size specifies the size of the file in bytes.
If argument err is not NULL, it will be used to store error information
in case of an error.
RETURN VALUES
On success, function dwarf_add_file_decl() returns the index value
generated for the source file. In case of an error, function
dwarf_add_file_decl() returns DW_DLV_NOCOUNT and sets the argument err.
ERRORS
Function dwarf_add_file_decl() can fail with:
[DW_DLE_ARGUMENT] Either arguments dbg or name was NULL.
[DW_DLE_ARGUMENT] The length of the NUL-teminated string pointed to by
argument name was 0.
[DW_DLE_MEMORY] An out of memory condition was encountered during the
execution of the function.
