POSIX Subroutine: Gets the value stored in a component (or field) of a structure.
Module: USE IFPOSIX
Syntax
CALL PXF<TYPE>GET (jhandle, compname, value, ierror)
CALL PXF<TYPE>GET (jhandle, compname, value, ilen, ierror) ! syntax when <TYPE> is STR
<TYPE>
A placeholder for one of the following values:
| Value | Data Type | Routine Name |
|---|---|---|
| INT | INTEGER(4) | PXFINTGET |
| REAL | REAL(4) | PXFREALGET |
| LGCL | LOGICAL(4) | PXFLGCLGET |
| STR | CHARACTER*(*) | PXFSTRGET |
| CHAR | CHARACTER(1) | PXFCHARGET |
| DBL | REAL(8) | PXFDBLGET |
| INT8 | INTEGER(8) | PXFINT8GET |
jhandle
(Input) INTEGER(4). A handle of a structure.
compname
(Input) Character. The name of the component (or field) of the structure to retrieve data from.
value
(Output) A variable, whose data type depends on the value of <TYPE>. See the table above for the data types for each value; for example, if the value for <TYPE> is INT, the data type is INTEGER(4). Stores the value of the component (or field).
ilen
(Output) INTEGER(4). This argument can only be used when <TYPE> is STR (PXFSTRGET). Stores the length of the returned string.
ierror
(Output) INTEGER(4). The error status.
If successful, ierror is set to zero; otherwise, an error code.
The PXF<TYPE>GET subroutines retrieve the value from component (or field) compname of the structure associated with handle jhandle into variable value.
