2 Intel Fortran Libraries ReferenceConstant_SC_PHYS_PAGES_SC_AVPHYS_PAGESDescriptionIndicates the number of pages of physical memory. Note that it ispossible for the product of this value and the value of_SC_PAGE_SIZE to overflow.Indicates the number of currently available pages of physicalmemory.1. L*X only2. The corresponding POSIX macro is STREAM_MAX.3. The corresponding POSIX macro is EXPR_NEST_MAX.On Linux* systems, the corresponding macros are defined in . The values forargument name can be obtained by using PXFCONST or IPXFCONST when passing the stringnames of predefined macros in .See Also: “IPXFCONST”, “PXFCONST”PXFTCDRAINPOSIX Subroutine: Waits until all output written has been transmitted.
