Error handling library.
void ccp4_error | ( | const char * | ) |
Print out passed message and internal message based upon ccp4_errno "message : error message "
message | (const char *) |
References ccp4_errno, and ccp4_strerror().
Referenced by ccp4_fatal().
void ccp4_fatal | ( | const char * | ) |
Wrapper for ccp4_error which also calls exit(1)
message | (const char *) |

int ccp4_liberr_verbosity | ( | int | iverb | ) |
Function to set verbosity level for messages from ccp4_signal. Currently just off (0) and on (1). It should be generalised to be able to switch individual components on and off, i.e. replace 1 by a mask. cf. ccp4VerbosityLevel which sets the verbosity level for ccp4printf These are separate as they may be used differently.
iverb | If >= 0 then set the verbosity level to the value of iverb. If < 0 (by convention -1) then report current level. |

void ccp4_signal | ( | const int | , |
const char * | const, | ||
void(*)() | |||
) |
Routine to set ccp4_errno and print out message for error tracing. This should be the only way in which ccp4_errno is set. See error codes above for levels and systems. A callback with prototype void function(void) may also be passed to the routine. Note: FATAL calls exit(1). If ccp4_liberr_verbosity returns 0, then ccp4_signal sets ccp4_errno and returns without doing anything else.

const char* ccp4_strerror | ( | int | ) |
Obtain character string based upon error code. Typical use ccp4_strerror(ccp4_errno) The returned string is statically allocated in the library_err.c file and should not be freed.
