A ##[[KeyPgLongint|Longint]]## variable holding a binary copy of the input variable.
Returns a 64-bit ##[[KeyPgLongint|Longint]]## value using the binary data contained in a ##[[KeyPgDouble|Double]]##, or a ##[[KeyPgString|String]]## of at least eight bytes in length. A value of zero (##0##) is returned if the string is less than eight bytes in length.
##**Cvlongint**## is used to convert 8-byte strings created with ##[[KeyPgMklongint|Mklongint]]##.
This function can also be used to convert 64-bit integer values from a memory or file buffer without the need for a ##[[KeyPgType|Type]]## structure. However, just as with the type structure, special care should be taken when using ##**Cvlongint**## to convert strings that have been read from a buffer.

[[KeyPgDeclare declare]] [[KeyPgFunction function]] **Cvlongint** ( [[KeyPgByref byref]] //str// [[KeyPgAs as]] [[KeyPgConstQualifier const]] [[KeyPgString string]] ) [[KeyPgAs as]] [[KeyPgLongint longint]]
A [[KeyPgString string]] exactly eight bytes in length with a binary copy of a long integer variable stored in it.
A [[KeyPgLongint longint]] variable to copy the binary copy of a long integer to.
Does a binary copy from an 8-byte-string to a longint variable. The result will have a sense only if the string contained a correctly formatted longint, as the one generated by ##[[KeyPgMklongint Mklongint]]##
This function is useful to read numeric values from buffers without using a ##[[KeyPgType Type]]## definition.
