- The PPXXFFSSIIGGPPRROOCCMMAASSKK subroutine uses ssiiggpprrooccmmaasskk(2) to store the set of
- signals blocked from delivery and pending for the calling process.
-
- The following is a list of arguments for this routine:
-
- _i_h_o_w A default integer input variable containing the manner in
- which the set is changed. The possible values are:
-
- SSIIGG__BBLLOOCCKK Add to current mask set
-
- SSIIGG__UUNNBBLLOOCCKK Delete from current mask set
-
- SSIIGG__SSEETTMMAASSKK Replace current mask set
-
- This argument is ignored if _j_o_s_i_g_s_e_t is NULL. If _i_h_o_w is
- zero, the current set is not changed.
-
- On IRIX systems, the value may also be set to SSIIGG__NNOOPP, which
- does not alter the current mask set. This value is
- equivalent to providing a NULL handle for _j_o_s_i_g_s_e_t.
-
- _j_s_i_g_s_e_t A default integer input variable containing a handle created
- by PPXXFFSSTTRRUUCCTTCCRREEAATTEE((_s_i_g_s_e_t,,......)). If nonzero, the handle
- points to a set of signals that can be used to change the
- currently blocked set.
-
- _j_o_s_i_g_s_e_t A default integer output variable containing a handle
- created by PPXXFFSSTTRRUUCCTTCCRREEAATTEE((_s_i_g_s_e_t,,......)). If nonzero, the
- handle will be set to the currently blocked signal set. If
- zero, the currently blocked signal set will not be changed
- and the value of _i_h_o_w is ignored.
-
- _i_e_r_r_n_o A default integer output variable that contains zero if
- PPXXFFSSIIGGPPPPRROOCCMMAASSKK was successful and nonzero if
- PPXXFFSSIIGGPPPPRROOCCMMAASSKK was not successful.
-
- This subroutine may return any of the following error values:
-
- EEFFAAUULLTT The _j_s_i_g_s_e_t or _j_o_s_i_g_s_e_t argument points outside the
- allocated space.
-
- EEIINNVVAALL The value of _i_h_o_w is an invalid or unsupported
- operation.
-
- EEBBAADDHHAANNDDLLEE The _j_s_i_g_s_e_t argument is invalid.
-
- On IRIX systems, this routine is in lliibbffoorrttrraann..ssoo which is linked by
- default when compiling programs with the MIPSpro 7 Fortran 90 compiler
- or when compiling programs with the --ccrraayylliibbss option to the MIPSpro
- F77 compiler.
-
- When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
- UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
- kind unless documented otherwise. On UNICOS and UNICOS/mk, default
- kind is KKIINNDD==88 for integer, real, complex, and logical arguments; on
- IRIX systems, the default kind is KKIINNDD==44.
