# Generate query_config.c
|
|
|
|
#
|
|
|
|
# The file query_config.c contains a C function that can be used to check if
|
|
|
|
# a configuration macro is defined and to retrieve its expansion in string
|
|
|
|
# form (if any). This facilitates querying the compile time configuration of
|
|
|
|
# the library, for example, for testing.
|
|
|
|
#
|
|
|
|
# The query_config.c is generated from the current configuration at
|
|
|
|
# include/mbedtls/config.h. The idea is that the config.h contains ALL the
|
|
|
|
# compile time configurations available in Mbed TLS (commented or uncommented).
|
|
|
|
# This script extracts the configuration macros from the config.h and this
|
|
|
|
# information is used to automatically generate the body of the query_config()
|
|
|
|
# function by using the template in scripts/data_files/query_config.fmt.
|
|
|
|
#
|
|
|
|
# Usage: ./scripts/generate_query_config.pl without arguments
