31 These are functions pertaining to core files.
40 bfd_core_file_failing_command
43 const char *bfd_core_file_failing_command (bfd *abfd);
46 Return a read-only string explaining which program was running
47 when it failed and produced the core file @var{abfd}.
52 bfd_core_file_failing_command (bfd *abfd)
54 if (abfd->format != bfd_core)
56 bfd_set_error (bfd_error_invalid_operation);
59 return BFD_SEND (abfd, _core_file_failing_command, (abfd));
64 bfd_core_file_failing_signal
67 int bfd_core_file_failing_signal (bfd *abfd);
70 Returns the signal number which caused the core dump which
71 generated the file the BFD @var{abfd} is attached to.
75 bfd_core_file_failing_signal (bfd *abfd)
77 if (abfd->format != bfd_core)
79 bfd_set_error (bfd_error_invalid_operation);
82 return BFD_SEND (abfd, _core_file_failing_signal, (abfd));
90 int bfd_core_file_pid (bfd *abfd);
94 Returns the PID of the process the core dump the BFD
95 @var{abfd} is attached to was generated from.
99 bfd_core_file_pid (bfd *abfd)
101 if (abfd->format != bfd_core)
103 bfd_set_error (bfd_error_invalid_operation);
106 return BFD_SEND (abfd, _core_file_pid, (abfd));
112 core_file_matches_executable_p
115 bfd_boolean core_file_matches_executable_p
116 (bfd *core_bfd, bfd *exec_bfd);
119 Return <<TRUE>> if the core file attached to @var{core_bfd}
120 was generated by a run of the executable file attached to
121 @var{exec_bfd}, <<FALSE>> otherwise.
125 core_file_matches_executable_p (bfd *core_bfd, bfd *exec_bfd)
127 if (core_bfd->format != bfd_core || exec_bfd->format != bfd_object)
129 bfd_set_error (bfd_error_wrong_format);
133 return BFD_SEND (core_bfd, _core_file_matches_executable_p,

139 generic_core_file_matches_executable_p
142 bfd_boolean generic_core_file_matches_executable_p
143 (bfd *core_bfd, bfd *exec_bfd);
146 Return TRUE if the core file attached to @var{core_bfd}
147 was generated by a run of the executable file attached
148 to @var{exec_bfd}. The match is based on executable
151 Note: When not able to determine the core file failing
152 command or the executable name, we still return TRUE even
153 though we're not sure that core file and executable match.
154 This is to avoid generating a false warning in situations
155 where we really don't know whether they match or not.

165 if (exec_bfd == NULL || core_bfd == NULL)
168 /* The cast below is to avoid a compiler warning due to the assignment
169 of the const char * returned by bfd_core_file_failing_command to a
170 non-const char *. In this case, the assignement does not lead to
171 breaking the const, as we're only reading the string. */
