58 functions locate the descriptive message
59 string for a signal number.
63 function accepts a signal number argument
65 and returns a pointer to the corresponding message string.
69 function accepts a signal number argument
71 and writes it to the standard error.
76 and does not point to the null character,
78 is written to the standard error file descriptor
79 prior to the message string,
80 immediately followed by a colon and a space.
81 If the signal number is not recognized
87 The message strings can be accessed directly
88 through the external array
90 indexed by recognized signal numbers.
94 contains short, lower-case abbreviations for signals
95 which are useful for recognizing signal names
99 contains a count of the strings in
103 Note that the defined variable
105 will typically be the same as
107 but might be different due to newer or older kernels and newer or
108 older libc libraries. For maximum portability you must use
110 to limit-check the above arrays. Additionally, you should check
113 array entries and generate a generic signal name in those cases.
