Function: %bytevector-s8-index criterion bv start past

Function: %bytevector-u8-index criterion bv start past

Function: %bytevector-s8-index-right criterion bv start past

Function: %bytevector-u8-index-right criterion bv start past

Macro: bytevector-s8-index B criterion

Macro: bytevector-u8-index B criterion

Macro: bytevector-s8-index-right B criterion

Macro: bytevector-u8-index-right B criterion

Search through the bytevector from the left or right, returning the index of the first occurrence of a byte which matches the criterion:

• If criterion is an exact integer: the byte has to be equal to it.
• If criterion is a character: the byte has to be equal to it.
• If criterion is a character set: the byte, interpreted as ASCII character, has to be contained in it.
• If criterion is a procedure: the procedure applied to the byte must return true.

If no match is found: return #f.

Function: %bytevector-s8-skip criterion bv start past

Function: %bytevector-u8-skip criterion bv start past

Function: %bytevector-s8-skip-right criterion bv start past

Function: %bytevector-u8-skip-right criterion bv start past

Macro: bytevector-s8-skip B criterion

Macro: bytevector-u8-skip B criterion

Macro: bytevector-s8-skip-right B criterion

Macro: bytevector-u8-skip-right B criterion

Search through the bytevector from the left or right, returning the index of the first occurrence of a byte which does not match the criterion:

• If criterion is an exact integer: the byte has to be different from it.
• If criterion is a character: the byte has to be different from it.
• If criterion is a character set: the byte, interpreted as ASCII character, must not be contained in it.
• If criterion is a procedure: the procedure applied to the byte must return false.

If no match is found: Return #f.

Function: %bytevector-s8-count criterion bv start past

Function: %bytevector-u8-count criterion bv start past

Macro: bytevector-s8-count B criterion

Macro: bytevector-u8-count B criterion

Return a count of the number of bytes in bv that satisfy the criterion argument:

• If criterion is an exact integer: the byte has to be equal to it.
• If criterion is a character: the byte has to be equal to it.
• If criterion is a character set: the byte, interpreted as ASCII character, has to be contained in it.
• If criterion is a procedure: the procedure applied to the byte must return true.

Function: %bytevector-s8-contains bv1 start1 past1 bv2 start2 past2

Function: %bytevector-u8-contains bv1 start1 past1 bv2 start2 past2

Function: %bytevector-s8-contains-ci bv1 start1 past1 bv2 start2 past2

Function: %bytevector-u8-contains-ci bv1 start1 past1 bv2 start2 past2

Macro: bytevector-s8-contains B1 B2

Macro: bytevector-u8-contains B1 B2

Macro: bytevector-s8-contains-ci B1 B2

Macro: bytevector-u8-contains-ci B1 B2

Return true if the subvector B1 contains the subvector B2, else return #f. The return value is the index in the bytevector, not in the subvector.
