| | 4 | quis \- remember the program's name for use in messages |
| | 5 | .SH SYNOPSIS |
| | 6 | .nf |
| | 7 | .B "#include <mLib/quis.h>" |
| | 8 | |
| | 9 | .BI "void ego(const char *" p ); |
| | 10 | .B "const char *quis(void);" |
| | 11 | .B "const char *QUIS;" |

| | 13 | .SH DESCRIPTION |
| | 14 | The |
| | 15 | .B ego |
| | 16 | function should be called early in your program's initialization |
| | 17 | sequence, with the value of |
| | 18 | .B argv[0] |
| | 19 | as its argument. It will strip away leading path components, and a |
| | 20 | leading `\-' character (in case the program was called as a login |
| | 21 | shell), and keep the resulting short name for later. |
| | 22 | .PP |
| | 23 | The |
| | 24 | .B quis |
| | 25 | function returns the stored program name. There is also a macro |
| | 26 | .B QUIS |
| | 27 | which expands to the name of a global variable whose value is the string |
| | 28 | returned by |
| | 29 | .BR quis() . |
| | 30 | .PP |
| | 31 | Don't ask why it's done this way. There are raisins, but they're mostly |
| | 32 | hysterical. |
| | 33 | .PP |
| | 34 | The program name is used in the messages produced by the |
| | 35 | .BR die (3mLib) |
| | 36 | and |
| | 37 | .BR moan (3mLib) |
| | 38 | functions. |
