Verifies that attribute values are within range.

int attrval (uniquetype, pattr, errattr) char * uniquetype; char * pattr; char ** errattr;
|uniquetype||Identifies the predefined device object, which is a pointer to a character string of the form class/subclass/type .|
|pattr||Points to a character string containing the attribute-value pairs to be validated, in the form attr1=val1 attr2=val2 .|
|errattr||Points a pointer to a null-terminated character string. On return from the attrval subroutine, this string will contain the names of invalid attributes, if any are found. Each attribute name is separated by spaces.|
The attrval subroutine is used to validate each of a list of input attribute values against the legal range. If no illegal values are found, this subroutine returns a value of 0. Otherwise, it returns the number of incorrect attributes.
If any attribute values are invalid, a pointer to a string containing a list of invalid attribute names is returned in the errattr parameter. These attributes are separated by spaces.
Allocation of the error buffer is done in the attrval subroutine. However, a character pointer (for example, char *errorb; ) must be declared in the calling routine. Thereafter, the address of that pointer is passed to the attrval subroutine (for example, attrval(...,&errorb); ) as one of the parameters.
|0||Indicates that all values are valid.|
|Nonzero||Indicates the number of erroneous attributes.|
