---|
| 9 | SYNOPSIS |
---|
| 10 | #include <stdio.h> |
---|
| 11 | void psignal(int <[signal]>, const char *<[prefix]>); |
---|
| 12 | |
---|
| 13 | DESCRIPTION |
---|
| 14 | Use <<psignal>> to print (on standard error) a signal message |
---|
| 15 | corresponding to the value of the signal number <[signal]>. |
---|
| 16 | Unless you use <<NULL>> as the value of the argument <[prefix]>, the |
---|
| 17 | signal message will begin with the string at <[prefix]>, followed by a |
---|
| 18 | colon and a space (<<: >>). The remainder of the signal message is one |
---|
| 19 | of the strings described for <<strsignal>>. |
---|
| 20 | |
---|
| 21 | RETURNS |
---|
| 22 | <<psignal>> returns no result. |
---|
| 23 | |
---|
| 24 | PORTABILITY |
---|
| 25 | POSIX.1-2008 requires <<psignal>>, but the strings issued vary from one |
---|
| 26 | implementation to another. |
---|
| 27 | |
---|
| 28 | Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>, |
---|
| 29 | <<lseek>>, <<read>>, <<sbrk>>, <<write>>. |
