#define ERR 2 |
A fatal error message.
Definition at line 44 of file gis/error.c.
#define MSG 0 |
A message.
Definition at line 32 of file gis/error.c.
#define WARN 1 |
A warning message.

void G_fatal_error | ( | const char * | msg, |
... | |||
) |
Print a fatal error message to stderr.
The output format depends on environment variable GRASS_MESSAGE_FORMAT
By default, the message is handled by an internal routine which prints the message to the screen. Using G_set_error_routine() the programmer can have the message handled by another routine. This is especially useful if the message should go to a particular location on the screen when using curses or to a location on a graphics device (monitor).
msg | string (cannot be NULL) |

Definition at line 67 of file gis/error.c.
void G_important_message | ( | const char * | msg, |
... | |||
) |
Print a message to stderr even in brief mode (verbosity=1)
Usually just G_percent()/G_clicker() would be shown at this level. This allows important non-error/warning messages to display as well.
The output format depends on environment variables GRASS_MESSAGE_FORMAT and GRASS_VERBOSE

int G_info_format | ( | void | ) |
Get current message format.
Maybe set to either "standard" or "gui" (normally GRASS takes care)

void G_set_error_routine | ( | int(*)(const char *, int) | error_routine | ) |
Establishes error_routine as the routine that will handle the printing of subsequent error messages.
error_routine | routine will be called like this: error_routine(msg, fatal) |
Definition at line 261 of file gis/error.c.
int G_sleep_on_error | ( | int | flag | ) |
Turn on/off no_sleep flag.
If flag is 0, then no pause will occur after printing an error or warning message. Otherwise the pause will occur.
flag | if non-zero/zero value is given G_sleep() will be activated/deactivated |
Definition at line 243 of file gis/error.c.
int G_suppress_warnings | ( | int | flag | ) |
Suppress printing a warning message to stderr.
flag | a warning message will be suppressed if non-zero value is given |
