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.
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.
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.
