Syntax
#pragma diag_default tag[,tag,...]
Where:
tag[,tag,...]
is a comma-separated list of diagnostic message numbers
specifying the messages whose severities are to be changed.
At least one diagnostic message number must be specified.
Example
// not #included deliberately
#pragma diag_error 223
void hello(void)
{
printf("Hello ");
}
#pragma diag_default 223
void world(void)
{
printf("world!\n");
}
Compiling this code with the option --diag_warning=223 generates diagnostic messages
to report that the function printf() is declared implicitly.
The effect of #pragma diag_default 223 is to return the severity of diagnostic message
223 to Warning severity, as specified by the --diag_warning command-line option.
