## Description Various utility functions. ## Functions ### xmlSecInit ()
    int
    xmlSecInit (void);
Initializes XML Security Library. The depended libraries (LibXML and LibXSLT) must be initialized before. #### Returns 0 on success or a negative value otherwise. ### xmlSecShutdown ()
    int
    xmlSecShutdown (void);
Clean ups the XML Security Library. #### Returns 0 on success or a negative value otherwise. ### xmlSecGetDefaultCrypto ()
    const xmlChar *
    xmlSecGetDefaultCrypto (void);
Gets the default crypto engine ("openssl", "nss", etc.) for the XML Security Library. #### Returns the default crypto engine ("openssl", "nss", etc.). ### xmlSecSetExternalEntityLoader ()
    void
    xmlSecSetExternalEntityLoader (xmlExternalEntityLoader entityLoader);
Wrapper for xmlSetExternalEntityLoader. #### Parameters
entityLoader | the new entity resolver function, or NULL to restore libxml2's default handler |
### xmlSecStrlen ()
    xmlSecSize
    xmlSecStrlen (const xmlChar *str);
Calcaulates the lenght of the string. #### Parameters
str | the string. |
#### Returns the length of the string. ### xmlSecCheckVersionExact
    #define             xmlSecCheckVersionExact()
Macro. Returns 1 if the loaded xmlsec library version exactly matches the one used to compile the caller, 0 if it does not or a negative value if an error occurs. ### xmlSecCheckVersion
    #define             xmlSecCheckVersion()
Macro. Returns 1 if the loaded xmlsec library version ABI compatible with the one used to compile the caller, 0 if it does not or a negative value if an error occurs. ### xmlSecCheckVersionExt ()
    int
    xmlSecCheckVersionExt (int major,
                           int minor,
                           int subminor,
                           xmlSecCheckVersionMode mode);
Checks if the loaded version of xmlsec library could be used. #### Parameters
major | the major version number. |
minor | the minor version number. |
subminor | the subminor version number. |
mode | the version check mode. |
#### Returns 1 if the loaded xmlsec library version is OK to use 0 if it is not or a negative value if an error occurs. ## Types and Values ### XMLSEC_DEPRECATED
    #define XMLSEC_DEPRECATED __attribute__((deprecated))
Marks function as deprecated. ### xmlSecPtr
    typedef void*                                   xmlSecPtr;
Void pointer. ### XMLSEC_SIZE_T_FMT
    #define XMLSEC_SIZE_T_FMT                      "%llu"
The only reason we need this is that MinGW doesn't recognize "`zu`" despite the fact that MSVC runtime supports it for 10+ years. ### xmlSecSize
    typedef size_t xmlSecSize;
Size of something. ### XMLSEC_SIZE_MIN
    #define XMLSEC_SIZE_MIN                         ((xmlSecSize)0)
### XMLSEC_SIZE_MAX
    #define XMLSEC_SIZE_MAX                         SIZE_MAX
### XMLSEC_SIZE_FMT
    #define XMLSEC_SIZE_FMT                         XMLSEC_SIZE_T_FMT
### xmlSecByte
    typedef unsigned char xmlSecByte;
One byte. ### enum xmlSecCheckVersionMode The xmlsec library version mode. #### Members
xmlSecCheckVersionExactMatch | the version should match exactly. |
xmlSecCheckVersionABICompatible | the version should be ABI compatible. |
