| 11 | .SH SYNOPSIS | |

| 13 | .B psignal(sig, s) | |
| 14 | .B unsigned sig; | |

| 19 | .SH DESCRIPTION | |
| 20 | .I Psignal | |
| 21 | produces a short message | |
| 22 | on the standard error file | |
| 23 | describing the indicated signal. | |
| 24 | First the argument string | |
| 25 | .I s | |
| 26 | is printed, then a colon, then the name of the signal | |
| 27 | and a new-line. | |
| 28 | Most usefully, the argument string is the name | |
| 29 | of the program which incurred the signal. | |
| 30 | The signal number should be from among those found | |
| 31 | in | |
| 32 | .IR <signal.h> . | |
| 33 | .PP | |
| 34 | To simplify variant formatting | |
| 35 | of signal names, the vector of message strings | |
| 36 | .I sys_siglist | |
| 37 | is provided; | |
| 38 | the signal number | |
| 39 | can be used as an index in this table to get the | |
| 40 | signal name without the newline. | |
| 41 | The define NSIG defined in | |
| 42 | .RI < signal.h > | |
| 43 | is the number of messages provided for in the table; | |
| 44 | it should be checked because new | |
| 45 | signals may be added to the system before | |
| 46 | they are added to the table. | |
