cProc procName, <attributes>, <autoSave>The cProc macro defines the name and attributes of a function.
procName
Specifies the name of the function.
attributes
Specifies the function type. This parameter can be a combination of the following types:
| Type | Description |
| NEAR | Near function. It can be called only from the segment in which it is defined. |
| FAR | Far function. It can be called from any segment. |
| PUBLIC | Public function. It can be externally declared in other source files. |
The default attribute is NEAR and private (that is, the function cannot be declared externally in other source files). The NEAR and FAR attributes cannot be used together. If more than one attribute is selected, angle brackets are required.
autoSave
Specifies a list of registers to be saved when the function is invoked and restored when exited. Any 8086 register can be specified.
If this function is called by a function written in C, it must save and restore the SI and DI registers.
The BP register is always saved, regardless of whether it is present in the list given by the autoSave parameter.
The following examples demonstrate the usage of the cProc macro:
cProc proc1, <FAR, ds,es>
cProc proc2, <NEAR,PUBLIC>
cProc proc3,,ds
