66 | * FCGI_Accept -- |
67 | * |
68 | * Accepts a new request from the HTTP server and creates |
69 | * a conventional execution environment for the request. |
70 | * |
71 | * If the application was invoked as a FastCGI server, |
72 | * the first call to FCGI_Accept indicates that the application |
73 | * has completed its initialization and is ready to accept |
74 | * a request. Subsequent calls to FCGI_Accept indicate that |
75 | * the application has completed its processing of the |
76 | * current request and is ready to accept a new request. |
77 | * |
78 | * If the application was invoked as a CGI program, the first |
79 | * call to FCGI_Accept is essentially a no-op and the second |
80 | * call returns EOF (-1). |
81 | * |
82 | * Results: |
83 | * 0 for successful call, -1 for error (application should exit). |
84 | * |
85 | * Side effects: |
86 | * If the application was invoked as a FastCGI server, |
87 | * and this is not the first call to this procedure, |
88 | * FCGI_Accept first performs the equivalent of FCGI_Finish. |
89 | * |
90 | * On every call, FCGI_Accept accepts the new request and |
91 | * reads the FCGI_PARAMS stream into an environment array, |
92 | * i.e. a NULL-terminated array of strings of the form |
93 | * ``name=value''. It assigns a pointer to this array |
94 | * to the global variable environ, used by the standard |
95 | * library function getenv. It creates new FCGI_FILE *s |
96 | * representing input from the HTTP server, output to the HTTP |
97 | * server, and error output to the HTTP server, and assigns these |
98 | * new files to stdin, stdout, and stderr respectively. |
99 | * |
100 | * DO NOT mutate or retain pointers to environ or any values |
101 | * contained in it (e.g. to the result of calling getenv(3)), |
102 | * since these are freed by the next call to FCGI_Finish or |
103 | * FCGI_Accept. In particular do not use setenv(3) or putenv(3) |
104 | * in conjunction with FCGI_Accept. |
