By default, the ASN1C compiler generates the following set of .c source files for a given ASN.1 module (note: the name of the module would be substituted for <moduleName>):
<moduleName>.c
common definitions and functions (for example,
asn1Free_<type>) and/or global value constant
definitions.
<moduleName>Enc.c
encode functions (asn1E_<type>)
<moduleName>Dec.c
decode functions (asn1D_<type>)
If additional options are used (such as –genPrint, -genCopy, etc), additional files will be generated:
<moduleName>Copy.c
copy functions, generated if –genCopy is
specified
<moduleName>Print.c
print functions, generated if –genPrint is
specified
<moduleName>Compare.c
comparison functions, generated if –genCompare is
specified
<moduleName>PrtToStr.c
print-to-string functions, generated if –genPrtToStr
is specified
<moduleName>PrtToStrm.c
print-to-stream functions, generated if
–genPrtToStrm is specified
<moduleName>Table.c
table constraint functions, generated if –genTable
option is specified
<moduleName>Test.c
test functions, generated if –genTest is
specified
If –genCopy, -genPrint, etc have a filename parameter then the code will be written to the given file instead of the default one. If the –cfile <filename> option is used and –genCopy, -genPrint, etc options do not have parameters then all code will be placed in one source file with name <filename>.
