| 27 | ?S:d_shmat: | |
| 28 | ?S: This variable conditionally defines the HAS_SHMAT symbol, which | |
| 29 | ?S: indicates to the C program that the shmat() routine is available. | |
| 30 | ?S:. | |
| 31 | ?S:shmattype: | |
| 32 | ?S: This symbol contains the type of pointer returned by shmat(). | |
| 33 | ?S: It can be 'void *' or 'char *'. | |
| 34 | ?S:. | |
| 35 | ?S:d_shmatprototype: | |
| 36 | ?S: This variable conditionally defines the HAS_SHMAT_PROTOTYPE | |
| 37 | ?S: symbol, which indicates that sys/shm.h has a prototype for | |
| 38 | ?S: shmat. | |
| 39 | ?S:. | |
| 40 | ?C:HAS_SHMAT: | |
| 41 | ?C: This symbol, if defined, indicates that the shmat() routine is | |
| 42 | ?C: available to attach a shared memory segment to the process space. | |
| 43 | ?C:. | |
| 44 | ?C:Shmat_t: | |
| 45 | ?C: This symbol holds the return type of the shmat() system call. | |
| 46 | ?C: Usually set to 'void *' or 'char *'. | |
| 47 | ?C:. | |
| 48 | ?C:HAS_SHMAT_PROTOTYPE: | |
| 49 | ?C: This symbol, if defined, indicates that the sys/shm.h includes | |
| 50 | ?C: a prototype for shmat(). Otherwise, it is up to the program to | |
| 51 | ?C: guess one. Shmat_t shmat _((int, Shmat_t, int)) is a good guess, | |
| 52 | ?C: but not always right so it should be emitted by the program only | |
| 53 | ?C: when HAS_SHMAT_PROTOTYPE is not defined to avoid conflicting defs. | |
