30 These are functions pertaining to core files.
39 bfd_core_file_failing_command
42 const char *bfd_core_file_failing_command (bfd *abfd);
45 Return a read-only string explaining which program was running
46 when it failed and produced the core file @var{abfd}.
51 bfd_core_file_failing_command (bfd *abfd)
53 if (abfd->format != bfd_core)
55 bfd_set_error (bfd_error_invalid_operation);
58 return BFD_SEND (abfd, _core_file_failing_command, (abfd));
63 bfd_core_file_failing_signal
66 int bfd_core_file_failing_signal (bfd *abfd);
69 Returns the signal number which caused the core dump which
70 generated the file the BFD @var{abfd} is attached to.
74 bfd_core_file_failing_signal (bfd *abfd)
76 if (abfd->format != bfd_core)
78 bfd_set_error (bfd_error_invalid_operation);
81 return BFD_SEND (abfd, _core_file_failing_signal, (abfd));
89 int bfd_core_file_pid (bfd *abfd);
93 Returns the PID of the process the core dump the BFD
94 @var{abfd} is attached to was generated from.
98 bfd_core_file_pid (bfd *abfd)
100 if (abfd->format != bfd_core)
102 bfd_set_error (bfd_error_invalid_operation);
105 return BFD_SEND (abfd, _core_file_pid, (abfd));
111 core_file_matches_executable_p
114 bfd_boolean core_file_matches_executable_p
115 (bfd *core_bfd, bfd *exec_bfd);
118 Return <<TRUE>> if the core file attached to @var{core_bfd}
119 was generated by a run of the executable file attached to
120 @var{exec_bfd}, <<FALSE>> otherwise.
124 core_file_matches_executable_p (bfd *core_bfd, bfd *exec_bfd)
126 if (core_bfd->format != bfd_core || exec_bfd->format != bfd_object)
128 bfd_set_error (bfd_error_wrong_format);
132 return BFD_SEND (core_bfd, _core_file_matches_executable_p,

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

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