EXTCENTRY(1)
NAME
extcentry - extract FORTRAN-callable entry points from a C file
SYNOPSIS
extcentry infile outfile
DESCRIPTION
extcentry is used to extract C functions for which FORTRAN-callable interface
routines (wrappers) are to be generated by the program mkf2c. extcentry
accepts as input any C file (infile), and outputs (to outfile) only those portions
which are surrounded by the special comments /* CENTRY */ and /* END-
CENTRY */.
The first step in generating a FORTRAN-to-C interface routine is to surround
only those C functions for which entry points are to be generated by these
special comments and to run the file through extcentry. The FORTRAN-to-C
intertace generator program mkf2c(1) can then be invoked on the resultant
file to generate the assembly language wrapper. This is necessary since
mkf2c(1) understands only a limited subset of the C grammar, and cannot
parse such constructs as external declarations, typedefs, and C-preprocessor
directives.
