NAME

mkc_check_decl - checks for define, function, variable, type or function prototype.

SYNOPSIS

mkc_check_decl <check_type> <what> [includes...] mkc_check_decl -h

DESCRIPTION

check_type is either define, variable, func[0-9], type, member or prototype. Depending on its value mkc_check_decl checks for define, variable, function with specified number of arguments, type or a member of structure in a specified header files includes by compiling a test program. As a result it prints either 1 (success) or 0 (failure) to stdout.

OPTIONS

-h display help message

ENVIRONMENT

CC Compiler. By default cc is used. CPPFLAGS, CFLAGS Options passed to the compiler, for example -I for additional directories that con‐ tain header files. MKC_VERBOSE If set to 1, verbose messages are output to stderr. MKC_SHOW_CACHED If set to 1 and MKC_VERBOSE is set to 1, cached results are output to stderr. MKC_COMMON_HEADERS List of header files to add to .c test program. MKC_CACHEDIR Directory where temporary and cache files are created. If unset they are created in a current directory. MKC_NOCACHE All results are cached unless MKC_NOCACHE variable is set to 1. MKC_DELETE_TMPFILES If set to 1, temporary files are removed.
